Nonparabolic effects in multiple quantum well structures and influence of external magnetic field on dipole matrix elements [PDF]

Electronics, 2015
We present a method of modeling of nonparabolic effects (NPE) in quantum nanostructures by using second order perturbation theory. We apply this model on multiple quantum well structures and consider the influence of external magnetic field on dipole ...

Thermally activated charge fluctuations in GaAs double quantum dots [PDF]

, 2014
In this thesis, laterally defined GaAs quantum dots and double quantum dots are investigated by means of real-time charge sensing. A quantum dot charge sensor, adjacent to the investigated double dot system, detects single electron tunneling with ...

Band Structure and Intersubband Transitions of Three-Layer Semiconductor Nanoplatelets

Nanomaterials, 2020
This paper presents the first general theory of electronic band structure and intersubband transitions in three-layer semiconductor nanoplatelets. We find a dispersion relation and wave functions of the confined electrons and use them to analyze the band

Decoherence in nanostructures and quantum systems [PDF]

Physica E: Low-dimensional Systems and Nanostructures, 2003
Decoherence phenomena are pervasive in the arena of nanostructures but perhaps even more so in the study of the fundamentals of quantum mechanics and quantum computation. Since there has been little overlap between the studies in both arenas, this is an attempt to bridge the gap.
