An exciton is a bound pair of negatively charged electron and positively charged hole
(electron vacancy within a solid), both of which are held together by their mutual Coulomb …

We investigated excitonic absorptions in a GaAs/AlAs/GaAs single barrier heterostructure
using both photocapacitance and photocurrent spectroscopies at room temperature …

We report on capacitance-voltage spectroscopy of self-assembled InAs quantum dots under
constant illumination. Besides the electronic and excitonic charging peaks in the spectrum …

Presence of coherent 'resonant'tunneling in quantum dot (zero-dimensional)-quantum well
(two-dimensional) heterostructure is necessary to explain the collective oscillations of …

Durch das stete Bestreben der Menschheit nach besseren Rechenmaschinen und
schnellerer Datenkommunikation war es in der Vergangenheit ein probates Mittel, die …

Recently, there has been a great deal of interest in the potential of perovskite materials for
white light emitting diodes (WLEDs). This is due to the remarkable optical properties of these …

We observed large enhancement of capacitance with strong voltage sensitivity in
InGaN/GaN multiple quantum wells with additional laser illuminations. We have found that …

Quantum oscillations of photocapacitance measured over a large area indicate manybody
cooperative phenomena of dipolar excitons. Presence and absence of splitting of excitonic …

We report quantum coherent oscillations of photocapacitance of a double-barrier resonant
tunneling heterostructure with bias at 10 K. Periodic presence and absence of sharp …
