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…
Charged impurity scattering in two-dimensional materials with ring-shaped valence bands: GaS, GaSe, InS, and InSe
Protik Das, Darshana Wickramaratne, Bishwajit Debnath +2
The singular density of states and the two Fermi wavevectors resulting from a ring-shaped or "Mexican hat" valence band give rise to unique trends in the charged impurity scatterin…
Exciton condensate in bilayer transition metal dichalcogenides: strong coupling regime
Bishwajit Debnath, Yafis Barlas, Darshana Wickramaratne +2
Exciton condensation in an electron-hole bilayer system of monolayer transition metal dichalcogenides is analyzed at three different levels of theory to account for screening and q…
Direct Observation of Acoustic Phonon Confinement in Free-Standing Semiconductor Nanowires
Fariborz Kargar, Bishwajit Debnath, Kakko Joona-Pekko +5
Similar to electron waves, the phonon states in semiconductors can undergo changes induced by external boundaries. Modification of acoustic phonon spectrum in structures with perio…
An Integrated Tantalum Sulfide - Boron Nitride - Graphene Oscillator: A Charge-Density-Wave Device Operating at Room Temperature
Guanxiong Liu, Bishwajit Debnath, Timothy R. Pope +3
The charge-density-wave (CDW) phase is a macroscopic quantum state consisting of a periodic modulation of the electronic charge density accompanied by a periodic distortion of the…
Acoustic Phonon Spectrum and Thermal Transport in Nanoporous Alumina Arrays
Fariborz Kargar, Sylvester Ramirez, Bishwajit Debnath +3
We report results of a combined investigation of thermal conductivity and acoustic phonon spectra in nanoporous alumina membranes with the pore diameter decreasing from D=180 nm to…
