Zero-field thermopower of a thin heterostructure membrane with a 2D electron gas
M. Schmidt, G. Schneider, Ch. Heyn +2
We study the low-temperature thermopower of micron sized, free-standing membranes containing a two-dimensional electron system. Suspended membranes of 320 nm thickness including a…

Thermopower of a 2D electron gas in suspended AlGaAs/GaAs heterostructures
M. Schmidt, G. Schneider, Ch. Heyn +2
We present thermopower measurements on a high electron mobility two-dimensional electron gas (2DEG) in a thin suspended membrane.We show that the small dimension of the membrane su…
