Density-tuned effective metal-insulator transitions in 2D semiconductor layers: Anderson localization or Wigner crystallization
Seongjin Ahn, Sankar Das Sarma
Electrons (or holes) confined in 2D semiconductor layers have served as model systems for studying disorder and interaction effects for almost 50 years. In particular, strong disor…
Hydrodynamics, viscous electron fluid, and Wiedeman-Franz law in 2D semiconductors
Seongjin Ahn, Sankar Das Sarma
Considering theoretically the transition between hydrodynamic and ballistic regimes in 2D semiconductors, we show that electrons in high-mobility 2D GaAs are by far the best system…
Anderson localization crossover in 2D Si systems: The past and the present
Seongjin Ahn, Sankar Das Sarma
Using Ioffe-Regel-Mott (IRM) criterion for strong localization crossover in disordered doped 2D electron systems, we theoretically study the relationships among the three key exper…
Temperature dependent resistivity in the doped two dimensional metallic phase of mTMD bilayers
Seongjin Ahn, Sankar Das Sarma
Two recent experiments from Cornell and Columbia have reported insulator-to-metal transitions in two-dimensional (2D) moiré transition metal dichalcogenides (mTMD) induced by dopin…
Planckian properties of 2D semiconductor systems
Seongjin Ahn, Sankar Das Sarma
We describe and discuss the low-temperature resistivity (and the temperature-dependent inelastic scattering rate) of several different doped 2D semiconductor systems from the persp…
