Evidence for Two Different Solid Phases of Two Dimensional Electrons in High Magnetic Fields

Yong P. Chen, R. M. Lewis, L. W. Engel +5

We have performed RF spectroscopy on very high quality two dimensional electron systems in the high magnetic field insulating phase, usually associated with a Wigner solid (WS) pin…

Evidence For Heavy Hole and Light Hole Current Separation in P-Type Resonant Tunneling Diodes With Prewells

R. M. Lewis, H. P. Wei, S. Y. Lin +1

We investigate the transport of holes through $A l A s / I n_{.10} G a_{.90} A s$ resonant tunneling diodes which utilize $I n_{x} G a_{1 - x} A s$ prewells in the emitter with $x = 0, .10,$ and $.20$ .…
