Patent number: 11942282Abstract: A thermally sensitive ionic redox transistor comprises a channel, a reservoir layer, and an electrolyte layer disposed between the channel and the reservoir layer. A conductance of the channel is varied by changing concentration of ions in the channel layer. The electrolyte layer is configured to undergo a state change at a state transition temperature. Below the state transition temperature, ions in the electrolyte layer are substantially immobile. Above the state transition temperature, ions can move freely between the reservoir layer and the channel across the electrolyte layer in response to a voltage being applied between the channel and the reservoir layer. When the device is cooled below the state transition temperature or temperature range, the ions are trapped in one or more of the layers because the electrolyte layer loses its ionic conductivity. A state of the redox transistor can be read by measuring the conductance of the channel.Type: GrantFiled: July 13, 2021Date of Patent: March 26, 2024Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: David Scott Ashby, Elliot James Fuller, Albert Alec Talin, Yiyang Li

Patent number: 11930723Abstract: An ionic redox transistor comprises a solid channel, a solid reservoir layer, and a solid electrolyte layer disposed between the channel and the reservoir layer. The channel exhibits a substantially linear current-voltage relationship in a first range of voltages, and a nonlinear current-voltage relationship in a second range of voltages that is greater than the first range of voltages. One or both of the substantially linear current-voltage relationship or the nonlinear current-voltage relationship of the channel is varied by changing the concentration of ions such as oxygen vacancies in the channel. Ion or vacancy transport between the channel and the reservoir layer across the electrolyte layer occurs in response to applying a voltage between the channel and the reservoir layer. Subject to the first range of voltages, the channel can function as a synapse device. Subject to the second range of voltages, the channel can function as a neuron device.Type: GrantFiled: November 9, 2021Date of Patent: March 12, 2024Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Albert Alec Talin, Elliot James Fuller, Christopher Bennett, Tianyao Xiao, Matthew Marinella, Suhas Kumar

Publication number: 20240072231Abstract: Custom-form batteries can supply complex, practical systems with an optimal energy density that wouldn't otherwise be possible using traditional battery form-factors. For example, iron disulfide (FeS2) is a prominent conversion cathode of commercial interest. 3D direct-ink write (DIW) printing of FeS2 inks can be used to produce ridged cathodes from the filamentary extrusion of highly concentrated FeS2 inks (60-70% solids). These ridged cathodes exhibit optimal power, uniformity, and stability when cycled at higher rates (in excess of C/10). Meanwhile, functional cells with custom-form wave-shaped electrodes (e.g., printed FeS2 cathodes and pressed lithium anodes) exhibit improved performance over similar cells in planar configurations. In general, the DIW of concentrated inks is a viable path toward the making of custom-form conversion lithium batteries. More broadly, ridging is found to optimize rate capability.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Jorge Antonio Cardenas, John Paul Bullivant, Katharine Lee Harrison, Adam W.

Patent number: 11450802Abstract: A thermally sensitive ionic redox transistor comprises a solid channel, a solid reservoir layer, and a solid electrolyte layer disposed between the channel and the reservoir layer. A conductance of the channel is varied by changing the concentration of ions such as oxygen vacancies in the channel layer. Ionic conductivity of the gate, electrolyte, and channel layers increase with increasing temperature. Ion or vacancy transport between the channel and the reservoir layer across the electrolyte layer occurs in response to applying a voltage between the channel and the reservoir layer when the device is heated to an elevated temperature. When the device is cooled below the elevated temperature, the ions are trapped in one or more of the layers because the materials lose their ionic conductivity. A state of the redox transistor can be read by measuring the conductance of the channel.Type: GrantFiled: April 21, 2020Date of Patent: September 20, 2022Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Yiyang Li, Albert Alec Talin, Elliot James Fuller

Patent number: 10429343Abstract: Various technologies pertaining to a transistor having a variable-conductance channel with a non-volatile tunable conductance are described herein. The transistor comprises source and drain electrodes separated by a conducting channel layer. The conducting channel layer is separated from an electrochemical gate (ECG) layer by an electrolyte layer that prevents migration of electrons between the channel and the ECG but allows ion migration. When a voltage is applied between the channel and the ECG, electrons flow from one to the other, which causes a migration of ions from the channel to the ECG or vice versa. As ions move into or out of the channel layer, the conductance of the channel changes. When the voltage is removed, the channel maintains its conductance state.Type: GrantFiled: February 9, 2017Date of Patent: October 1, 2019Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Albert Alec Talin, Farid El Gabaly Marquez, Elliot James Fuller, Sapan Agarwal

Patent number: 9947379Abstract: Devices and methods for non-volatile analog data storage are described herein. In an exemplary embodiment, an analog memory device comprises a potential-carrier source layer, a barrier layer deposited on the source layer, and at least two storage layers deposited on the barrier layer. The memory device can be prepared to write and read data via application of a biasing voltage between the source layer and the storage layers, wherein the biasing voltage causes potential-carriers to migrate into the storage layers. After initialization, data can be written to the memory device by application of a voltage pulse between two storage layers that causes potential-carriers to migrate from one storage layer to another. A difference in concentration of potential carriers caused by migration of potential-carriers between the storage layers results in a voltage that can be measured in order to read the written data.Type: GrantFiled: October 6, 2016Date of Patent: April 17, 2018Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Farid El Gabaly Marquez, Albert Alec Talin

Patent number: 7608367Abstract: The present invention is directed to the use of vitreous carbon as a substrate material for providing masks for X-ray lithography. The new substrate also enables a small thickness of the mask absorber used to pattern the resist, and this enables improved mask accuracy. An alternative embodiment comprised the use of vitreous carbon as a LIGA substrate wherein the VC wafer blank is etched in a reactive ion plasma after which an X-ray resist is bonded. This surface treatment provides a surface enabling good adhesion of the X-ray photoresist and subsequent nucleation and adhesion of the electrodeposited metal for LIGA mold-making while the VC substrate practically eliminates secondary radiation effects that lead to delamination of the X-ray resist form the substrate, the loss of isolated resist features, and the formation of a resist layer adjacent to the substrate that is insoluble in the developer.Type: GrantFiled: July 28, 2005Date of Patent: October 27, 2009Assignee: Sandia CorporationInventors: Georg Aigeldinger, Dawn M.
