Millimeter wave transmission spectroscopy of two-dimensional electron and hole systems
In order to explore how electrons and holes in 2D semiconductors behave at 3He temperatures under millimeter wave irradiation, we developed a new probe and measurement technique. Our samples are specially grown high-mobility ...
Transport Properties of Topological Phases in Broken Gap Indium Arsenide/Gallium Antimonide Based Quantum Wells
The quantum Spin Hall Insulator (QSHI) is a two-dimensional variant of a novel class of materials characterized by topological order, whose unique properties have recently triggered much interest and excitement in the ...
Experimental studies of the fractional quantum Hall effect and the Wigner solids
This Ph.D. thesis is composed of two parts: the first part is concerned with electron transport in the higher Landau levels (LL) in a two-dimensional electron system (2DES); the second part is focused on the Wigner Crystal ...
5/2 state in high election density gallium arsenide/aluminum gallium arsenide quantum well
This Master of Science Thesis is concerned with electronic transport in the higher Landau levels (LL) in a two-dimensional electron system, where novel many-body electronic phases have been observed. Particular attention ...
Quantum transport in inverted indium arsenide/gallium antimonide composite quantum wells
We present a comprehensive study of low temperature quantum transport in double gated InAs/GaSb composite quantum wells. Recently, it has been proposed that this system in inverted regime should exhibit the topologically ...
Quantum transport in spatially modulated two-dimensional electron and hole systems
Two-dimensional electron (2DES) and hole (2DHS) systems have attracted intense research attentions in past decades. A 2DES or 2DHS modulated by one-dimensional or two-dimensional spatially periodic potential shows particular ...
