Current Oscillations in Quasi-2D Charge-Density-Wave 1T-TaS2 Devices: Revisiting the 'Narrow Band Noise' Concept

Autor: Geremew, Adane K., Rumyantsev, Sergey, Lake, Roger, Balandin, Alexander A.

Publikováno v: Applied Physics Letters, 116, 163101 (2020)

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 frequency of the oscillations on the current resemble closely the "narro

Low-Frequency Noise Spectroscopy of Charge-Density-Wave Phase Transitions in Vertical Quasi-2D Devices

Autor: Salgado, Ruben, Mohammadzadeh, Amirmahdi, Kargar, Fariborz, Geremew, Adane, Huang, Chun-Yu, Bloodgood, Matthew A., Rumyantsev, Sergey, Salguero, Tina T., Balandin, Alexander A.

Publikováno v: Applied Physics Express, 12, 037001 (2019)

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 study changes in the cross-plane electrical characteristics of the quasi-2
