Patent number: 12000861Abstract: Systems, apparatuses, and methods for realizing a peak-force scattering scanning near-field optical microscopy (PF-SNOM). Conventional scattering-type microscopy (s-SNOM) techniques uses tapping mode operation and lock-in detections that do not provide direct tomographic information with explicit tip-sample distance. Using a peak force scattering-type scanning near-field optical microscopy with a combination of peak force tapping mode and time-gated light detection, PF-SNOM enables direct sectioning of vertical near-field signals from a sample surface for both three-dimensional near-field imaging and spectroscopic analysis. PF-SNOM also delivers a spatial resolution of 5 nm and can simultaneously measure mechanical and electrical properties together with optical near-field signals.Type: GrantFiled: August 15, 2022Date of Patent: June 4, 2024Assignee: Lehigh UniversityInventors: Haomin Wang, Xiaoji Xu

Publication number: 20220347963Abstract: Resilient members having near-surface architectures including microstructures for controlling friction are provided. A film-terminated array of fibrils having a sharp film/fibril juncture exhibits an unexpectedly large enhancement of adhesion, static friction and sliding friction. The enhancement is provided against rough indenters. A film-terminated array of elongated ridges and valleys unexpectedly exhibits low adhesion, and an unexpectedly large enhancement of sliding friction. The film-terminated ridge/valley design provides an anisotropic structure with direction-dependent frictional properties. The increase in sliding friction force varies as a function of interfibrillar spacing, and corresponds to a mode in which buckling of the terminal film occurs. The near surface architectures may be designed with varying scales and varying parameters to provide performance characteristics tailored to various applications.Type: ApplicationFiled: May 13, 2022Publication date: November 3, 2022Applicant: Lehigh UniversityInventors: Anand Jagota, Ying Bai, Zhenping He, Chung-Yuen Hui, Benjamin Levrard

Patent number: 10115859Abstract: A symmetrical quantum well active layer provides enhanced internal quantum efficiency. The quantum well active layer includes an inner (central) layer and a pair of outer layers sandwiching the inner layer. The inner and outer layers have different thicknesses and bandgap characteristics. The outer layers are relatively thick and include a relatively low bandgap material, such as InGaN. The inner layer has a relatively lower bandgap material and is sufficiently thin to act as a quantum well delta layer, e.g., comprising approximately 6 ? or less of InN. Such a quantum well structure advantageously extends the emission wavelength into the yellow/red spectral regime, and enhances spontaneous emission. The multi-layer quantum well active layer is sandwiched by barrier layers of high bandgap materials, such as GaN.Type: GrantFiled: December 15, 2010Date of Patent: October 30, 2018Assignee: Lehigh UniversityInventors: Nelson Tansu, Hongping Zhao, Guangyu Liu, Gensheng Huang
