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…
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…
Anomalous Characteristics of the Generation - Recombination Noise in Quasi-One-Dimensional Van der Waals Nanoribbons
Adane K. Geremew, Sergey Rumyantsev, Matthew A. Bloodgood +2
We describe the low-frequency current fluctuations, i.e. electronic noise, in quasi-one-dimensional ZrTe3 van der Waals nanoribbons, which have recently attracted attention owing t…
