Nanomechanical Resonators: Toward Atomic Scale
Bo Xu, Pengcheng Zhang, Jiankai Zhu +14
The quest for realizing and manipulating ever smaller man-made movable structures and dynamical machines has spurred tremendous endeavors, led to important discoveries, and inspire…
Young's Modulus and Corresponding Orientation in β-Ga2O3 Thin Films Resolved by Nanomechanical Resonators
Xu-Qian Zheng, Hongping Zhao, Zhitai Jia +2
We report on the non-destructive measurement of Young's modulus of thin-film single crystal beta gallium oxide (beta-Ga2O3) out of its nanoscale mechanical structures by measuring…
Hexagonal Boron Nitride Phononic Crystal Waveguides
Yanan Wang, Jaesung Lee, Xu-Qian Zheng +2
Hexagonal boron nitride (h-BN), one of the hallmark van der Waals (vdW) layered crystals with an ensemble of attractive physical properties, is playing increasingly important roles…
Ultrawide Band Gap β-Ga2O3 Nanomechanical Resonators with Spatially Visualized Multimode Motion
Xu-Qian Zheng, Jaesung Lee, Subrina Rafique +4
Beta gallium oxide (β-Ga2O3) is an emerging ultrawide band gap (4.5 - 4.9 eV) semiconductor with attractive properties for future power electronics, optoelectronics, and sensors fo…
β-Ga2O3 NEMS Oscillator for Real-Time Middle Ultraviolet (MUV) Light Detection
Xu-Qian Zheng, Jaesung Lee, Subrina Rafique +5
We report on the first beta gallium oxide (β-Ga2O3) crystal feedback oscillator built by employing a vibrating β-Ga2O3 nanoresonator as the frequency reference for real-time middle…
Resolving and Tuning Mechanical Anisotropy in Black Phosphorus via Nanomechanical Multimode Resonance Spectromicroscopy
Zenghui Wang, Hao Jia, Xu-Qian Zheng +4
