Response to Parallel Magnetic Field of a Dilute 2D Electron System across the Metal-Insulator Transition
K. M. Mertes, D. Simonian, M. P. Sarachik +2
The response to a parallel magnetic field of the very dilute insulating two-dimensional system of electrons in silicon MOSFET's is dramatic and similar to that found on the conduct…
Comment on "Theory of metal-insulator transitions in gated semiconductors" (B. L. Altshuler and D. L. Maslov, Phys. Rev. Lett. 82, 145 (1999))
S. V. Kravchenko, M. P. Sarachik, D. Simonian
In a recent Letter, Altshuler and Maslov propose a model which attributes the anomalous temperature and field dependence of the resistivity of two-dimensional electron (or hole) sy…
Classical versus Quantum Effects in the B=0 Conducting Phase in Two Dimensions
S. V. Kravchenko, D. Simonian, K. Mertes +2
In the dilute two-dimensional electron system in silicon, we show that the temperature below which Shubnikov-de Haas oscillations become apparent is approximately the same as the t…
Comment on "Charged impurity scattering limited low temperature resistivity of low density silicon inversion layers" (Das Sarma and Hwang, cond-mat/9812216)
S. V. Kravchenko, D. Simonian, M. P. Sarachik
In a recent preprint cond-mat/9812216, Das Sarma and Hwang propose an explanation of the sharp decrease in resistivity at low temperatures which has been attributed to a transition…
Hopping Conduction in Uniaxially Stressed Si:B near the Insulator-Metal Transition
s. Bogdanovich, D. Simonian, S. V. Kravchenko +2
Using uniaxial stress to tune the critical density near that of the sample, we have studied in detail the low-temperature conductivity of p-type Si:B in the insulating phase very n…
Effect of Tilted Magnetic Field on the Anomalous H=0 Conducting Phase in High-Mobility Si MOSFETs
S. V. Kravchenko, D. Simonian, M. P. Sarachik +2
The suppression by a magnetic field of the anomalous H=0 conducting phase in high-mobility silicon MOSFETs is independent of the angle between the field and the plane of the 2D ele…
Reply to the Comment on "Electric Field Scaling at a B=0 Metal-Insulator Transition in Two Dimensions"
S. V. Kravchenko, D. Simonian, M. P. Sarachik
We note that data on Si/SiGe heterostructures, reported in the Comment of Ismail et al. (cond-mat/9707061) on our recent Letter (cond-mat/9608101), are insufficient to establish th…
The metal-insulator transition in Si:X: Anomalous response to a magnetic field
M. P. Sarachik, D. Simonian, S. V. Kravchenko +3
The zero-temperature magnetoconductivity of just-metallic Si:P scales with magnetic field, H, and dopant concentration, n, lying on a single universal curve. We note that Si:P, Si:…
Magnetic Field Suppression of the Conducting Phase in Two Dimensions
D. Simonian, S. V. Kravchenko, M. P. Sarachik
The anomalous conducting phase that has been shown to exist in zero field in dilute two-dimensional electron systems in silicon MOSFETs is driven into a strongly insulating state b…
