Absence of Localization in Certain Field Effect Transistors
S Washburn, D Popovic, KP Li +1
We review some experimental and theoretical results on the metal-to-insulator transition (MIT) observed at zero magnetic field (B=0) in several two-dimensional electron systems (2D…
Metal-Insulator Transition in a Low-Mobility Two-Dimensional Electron System
Dragana Popovic, A. B. Fowler, S. Washburn
We have varied the disorder in a two-dimensional electron system in silicon by applying substrate bias. When the disorder becomes sufficiently low, we observe the emergence of the…
Comment on ``Electric Field Scaling at B=0 Metal-Insulator Transition in Two Dimensions''
K. Ismail, J. O. Chu, Dragana Popovic +2
In a recent Letter, Kravchenko et al. [cond-mat/9608101] have provided evidence for a metal-insulator transition (MIT) in a two-dimensional electron system (2DES) in Si metal-oxide…
Minimum Metallic Mobility in a Two-Dimensional Electron Gas
Dragana Popovic, A. B. Fowler, S. Washburn
We report the observation of a metal-insulator transition in a two-dimensional electron gas in silicon. By applying substrate bias, we have varied the mobility of our samples, and…
