The first Nato Advanced Studies Institute entirely devoted to density functional theory was
held in Portugal in September 1983. The proceedings of this School, publis hed in early …

Twenty years ago active experimental studies of plasma oscillations in two-dimensional
electron systems (2DES's) in Si metal-oxide-semiconductor field-effect transistors and G a A …

Strong plasmon resonances have been observed in the terahertz transmission spectra (1–5
THz) of large-area slit-grating-gate AlGaN/GaN-based high-electron-mobility transistor …

Publisher Summary This chapter focuses on the basic aspects of intersubband transitions,
with the main emphasis on linear absorption. An expression for the intersubband absorption …

We study theoretically the elementary excitation spectrum in various one-dimensional
electron systems in the absence of a magnetic field. We first calculate the elementary …

At strong magnetic fields double-layer two-dimensional–electron-gas systems can form an
unusual broken symmetry state with spontaneous interlayer phase coherence. The system …

Physics of plasma oscillations and basic principles of plasmonic detection of terahertz
radiation in the grating-gate transistor structures with two-dimensional electron channels are …

We have investigated the radiative decay of hot two‐dimensional (2D) plasmons in Al0.
3Ga0. 7As/GaAs heterostructures by far‐infrared emission spectroscopy and determined the …

Two-dimensional plasmons were investigated by terahertz time domain spectroscopy
observing experimentally the distinctive minima and inflection points in the transmission …

We present a far-infrared-absorption study of electrons in lightly doped GaAs/Al x Ga 1− x As
superlattices. A grating coupler enables us to observe transitions that require an electric …
