Current Oscillations in Quasi-2D Charge-Density-Wave 1T-TaS2 Devices: Revisiting the "Narrow Band Noise" Concept
Adane K. Geremew, Sergey Rumyantsev, Roger Lake +1
We report on current oscillations in quasi two-dimensional (2D) 1T-TaS2 charge-density-wave devices. The MHz-frequency range of the oscillations and the linear dependence of the fr…
Low-Frequency Electronic Noise in Superlattice and Random-Packed Thin Films of Colloidal Quantum Dots
Adane Geremew, Caroline Qian, Alex Abelson +4
We report measurements of low-frequency electronic noise in ordered superlattice, weakly-ordered and random-packed thin films of 6.5 nm PbSe quantum dots prepared using several dif…
Thermal Properties of the Binary-Filler Composites with Few-Layer Graphene and Copper Nanoparticles
Zahra Barani, Amirmahdi Mohammadzadeh, Adane Geremew +5
The thermal properties of an epoxy-based binary composites comprised of graphene and copper nanoparticles are reported. It is found that the "synergistic" filler effect, revealed a…
Low Resistivity and High Breakdown Current Density of 10-nm Diameter van der Waals TaSe3 Nanowires by Chemical Vapor Deposition
Thomas A. Empante, Aimee Martinez, Michelle Wurch +8
Micron-scale single-crystal nanowires of metallic TaSe3, a material that forms -Ta-Se3-Ta-Se3- stacks separated from one another by a tubular van der Waals (vdW) gap, have been syn…
Electric Switching of the Charge-Density-Wave and Normal Metallic Phases in Tantalum Disulfide Thin-Film Devices
A. Geremew, S. Rumyantsev, F. Kargar +7
We report on switching among three charge-density-wave phases - commensurate, nearly commensurate, incommensurate - and the high-temperature normal metallic phase in thin-film 1T-T…
Low-Frequency Noise Spectroscopy of Charge-Density-Wave Phase Transitions in Vertical Quasi-2D Devices
Ruben Salgado, Amirmahdi Mohammadzadeh, Fariborz Kargar +6
We report results regarding the electron transport in vertical quasi-2D layered 1T-TaS2 charge-density-wave devices. The low-frequency noise spectroscopy was used as a tool to stud…
