Phonon States in NbTe and TaTe Quasi-One-Dimensional van der Waals Crystals
Zahra Ebrahim Nataj, Fariborz Kargar, Sergiy Krylyuk +7
We report the results of polarization-dependent Raman spectroscopy of phonon states in single-crystalline quasi-one-dimensional NbTe and TaTe van der Waals materials. The m…
Temperature Dependent Low-Frequency Noise Characteristics of NiO/GaO p-n Heterojunction Diodes
Subhajit Ghosh, Dinusha Herath Mudiyanselage, Fariborz Kargar +3
We report on the temperature dependence of the low-frequency electronic noise in NiO/GaO p-n heterojunction diodes. The noise spectral density is of the 1/f-type near r…
Optical and Acoustic Phonons in Turbostratic and Cubic Boron Nitride Thin Films on Diamond Substrates
Erick Guzman, Fariborz Kargar, Avani Patel +6
We report an investigation of the bulk optical, bulk acoustic, and surface acoustic phonons in thin films of turbostratic boron nitride (t-BN) and cubic boron nitride (c-BN) grown…
Conductance Fluctuations and Domain Depinning in Quasi-2D Charge-Density-Wave 1T-TaS Thin Films
Jonas O. Brown, Maedeh Taheri, Fariborz Kargar +5
We investigated the temperature dependence of the conductance fluctuations in thin films of the quasi-two-dimensional 1T-TaS van der Waals material. The conductance fluctuation…
Quantum Composites with the Functionality Defined by the Charge-Density-Wave Phase Transitions
Zahra Barani, Tekwam Geremew, Megan Stokey +7
We demonstrate a unique class of advanced materials - quantum composites based on polymers with fillers comprised of a van der Waals quantum material that reveals multiple charge-d…
Cryogenic Characteristics of Graphene Composites -- Evolution from Thermal Conductors to Thermal Insulators
Zahra Ebrahim Nataj, Youming Xu, Jonas Brown +4
The development of cryogenic semiconductor electronics and superconducting quantum computing requires composite materials that can provide both thermal conduction and thermal insul…
