Resonant Tunneling in Semiconductors
Physics and Applications
Book
Chapter
Resonant Raman scattering (RRS) by LO phonons is an optical method which provides information on the relationship between lattice-dynamical and electronic properties of crystals. A resonant enhancement of the ...
Chapter
We provide a perspective of the development of resonant tunneling over the last two decades. The work starts with a consideration of different semiconductor materials, proceeds to discuss the effects of band s...
Chapter
Diluted magnetic semiconductors offer the unique medium for the study of semiconductor physics and magnetism through the electron-ion exchange interaction. Precisely controlled heterostructures alter the band ...
Chapter
Quantum heterostructures have evolved over the last two decades to become a prominant, multi-disciplinary field in Condensed matter science. We provide, in this work, an overview of both the materials and phys...
Chapter
We review the results obtained from spectroscopy of low-dimensional systems using capacitance measurements. This technique has provided prima facie evidence for spatial quantization in quantum wires and quantu...
Chapter
Using magneto-optical methods, we have measured the pressure dependence of the energy difference between subbands in an InAs-GaSb superlattice associated with the GaSb valence and the InAs conduction bands, re...
Chapter and Conference Paper
We describe the InAs-GaSb superlattices and quantum wells with emphasis on their transport and optical properties. We include related structures of InAs-AlSb and GaSb-AlSb which are of interest in their own ri...
Chapter and Conference Paper
We report measurements of the magneto and Hall resistance in GaSb-InAs-GaSb heterostructures at magnetic fields up to 28T and temperatures as low as 0.005K. In addition to the quantized Hall effect, extraordin...
Chapter and Conference Paper
The quantum Hall effect in two-dimensional electron systems has been reported in a number of heterostructures,1–4 in which the Hall resistance, ρxy =h/νe2, shows plateaus at integral values of ν and the magneto-r...
