Patent number: 11518674Abstract: A system and method (referred to as the system) fabricates controllable atomic assemblies in two and three dimensions. The systems identify by a non-invasive imager, a local atomic structure, distribution of vacancies, and dopant atoms and modify, by a microscopic modifier, the local atomic structure, via electron beam irradiation. The systems store, by a knowledge base, cause-and-effect relationships based on a non-invasive imaging and electron scans. The systems detect, by detectors, changes in the local atomic structure induced by the electron irradiation; and fabricate, a modified atomic structure by a beam control software and feedback.Type: GrantFiled: February 3, 2020Date of Patent: December 6, 2022Assignee: UT-BATTELLE, LLCInventors: Sergei V.

Patent number: 11313878Abstract: Techniques for generating full-spatial resolution, full spectral resolution image(s) from a 3D spectral-data cube for any spectral value within a given spectral range are provided without requiring the acquisition of all full-spatial resolution, full spectral resolution data by an instrument. The 3D spectral-data cube is generated from a limited number of full-spatial resolution, sparse spectral resolution data and a sparse-spatial resolution, full-spectral resolution data of the same area of the sample. The use of the 3D spectral-data cube reduces the data acquisition time.Type: GrantFiled: April 16, 2021Date of Patent: April 26, 2022Assignee: UT-BATTELLE, LLCInventors: Olga S.

Patent number: 10400351Abstract: A method for sculpting crystalline oxide structures for bulk nanofabrication is provided. The method includes the controlled electron beam induced irradiation of amorphous and liquid phase precursor solutions using a scanning transmission electron microscope. The atomically focused electron beam includes operating parameters (e.g., location, dwell time, raster speed) that are selected to provide a higher electron dose in patterned areas and a lower electron dose in non-patterned areas. Concurrently with the epitaxial growth of crystalline features, the present method includes scanning the substrate to provide information on the size of the crystalline features with atomic resolution. This approach provides for atomic level sculpting of crystalline oxide materials from a metastable amorphous precursor and the liquid phase patterning of nanocrystals.Type: GrantFiled: September 7, 2017Date of Patent: September 3, 2019Assignee: UT-Battelle, LLCInventors: Albina Y.

Patent number: 10160645Abstract: Microwave AC conductivity may be improved or tuned in a material, for example, a dielectric or semiconductor material, by manipulating domain wall morphology in the material. Domain walls may be created, erased or reconfigured to control the AC conductivity, for example, for crafting circuit elements. The density and placement of domain walls may increase or decrease the AC conductivity and may control AC conduction pathways through the material. An electric potential applied to the material's surface may create a desired pattern of domain walls to meet desired AC conductivity criteria. Incline angle of the domain walls may be modified relative to a crystallographic axis of the material to temporarily or permanently modify or gate AC conductivity of the material. For example, the AC conductivity of the material may be gated by domain wall incline angle to increase, decrease or throttle current flowing through the material for an electronic circuit element.Type: GrantFiled: October 4, 2016Date of Patent: December 25, 2018Assignees: UT-BATTELLE, LLC, UNIVERSITY OF TENNESSEE RESEARCH FOUNDATIONInventors: Petro Maksymovych, Alexander Tselev, Sergei V.

Patent number: 9612257Abstract: Apparatus and methods are described for scanning probe microscopy and spectroscopy based on acquisition of full probe response. The full probe response contains valuable information about the probe-sample interaction that is lost in traditional scanning probe microscopy and spectroscopy methods. The full probe response is analyzed post data acquisition using fast Fourier transform and adaptive filtering, as well as multivariate analysis. The full response data is further compressed to retain only statistically significant components before being permanently stored.Type: GrantFiled: March 7, 2016Date of Patent: April 4, 2017Assignee: UT-Battelle, LLCInventors: Stephen Jesse, Alex Belianinov, Sergei V.

Patent number: 9541576Abstract: A system and method for electrochemical force microscopy are provided. The system and method are based on a multidimensional detection scheme that is sensitive to forces experienced by a biased electrode in a solution. The multidimensional approach allows separation of fast processes, such as double layer charging, and charge relaxation, and slow processes, such as diffusion and faradaic reactions, as well as capturing the bias dependence of the response. The time-resolved and bias measurements can also allow probing both linear (small bias range) and non-linear (large bias range) electrochemical regimes and potentially the de-convolution of charge dynamics and diffusion processes from steric effects and electrochemical reactivity.Type: GrantFiled: July 28, 2015Date of Patent: January 10, 2017Assignee: UT-Battelle, LLCInventors: Sergei V.

Patent number: 8752211Abstract: An excitation voltage biases an ionic conducting material sample over a nanoscale grid. The bias sweeps a modulated voltage with increasing maximal amplitudes. A current response is measured at grid locations. Current response reversal curves are mapped over maximal amplitudes of the bias cycles. Reversal curves are averaged over the grid for each bias cycle and mapped over maximal bias amplitudes for each bias cycle. Average reversal curve areas are mapped over maximal amplitudes of the bias cycles. Thresholds are determined for onset and ending of electrochemical activity. A predetermined number of bias sweeps may vary in frequency where each sweep has a constant number of cycles and reversal response curves may indicate ionic diffusion kinetics.Type: GrantFiled: August 3, 2012Date of Patent: June 10, 2014Assignee: UT-Battelle, LLCInventors: Sergei V.

Patent number: 8719961Abstract: A method and system for probing mobile ion diffusivity and electrochemical reactivity on a nanometer length scale of a free electrochemically active surface includes a control module that biases the surface of the material. An electrical excitation signal is applied to the material and induces the movement of mobile ions. An SPM probe in contact with the surface of the material detects the displacement of mobile ions at the surface of the material. A detector measures an electromechanical strain response at the surface of the material based on the movement and reactions of the mobile ions. The use of an SPM tip to detect local deformations allows highly reproducible measurements in an ambient environment without visible changes in surface structure. The measurements illustrate effective spatial resolution comparable with defect spacing and well below characteristic grain sizes of the material.Type: GrantFiled: November 8, 2011Date of Patent: May 6, 2014Assignee: UT-Battelle, LLCInventors: Sergei V.

Patent number: 8484759Abstract: An approach for the thermomechanical characterization of phase transitions in polymeric materials (polyethyleneterephthalate) by band excitation acoustic force microscopy is developed. This methodology allows the independent measurement of resonance frequency, Q factor, and oscillation amplitude of a tip-surface contact area as a function of tip temperature, from which the thermal evolution of tip-surface spring constant and mechanical dissipation can be extracted. A heating protocol maintained a constant tip-surface contact area and constant contact force, thereby allowing for reproducible measurements and quantitative extraction of material properties including temperature dependence of indentation-based elastic and loss moduli.Type: GrantFiled: August 17, 2010Date of Patent: July 9, 2013Assignee: UT-Battelle, LLCInventors: Stephen Jesse, Sergei V.
