Electronic properties in two dimensional quantum rings consisting of two nanoelements

Sahakyan A.S., Movsesyan R.M., Kocharian A.N., California State University Los Angeles, US

Electron spectrum and ground state properties in two dimensional confined quantum rings with R(1,2) radiuses (R1 les R2), consisting of the two different (material) nanoelements divided by two sectored finite size quantum wells with various [...]

Optimizing Quantum Well Solar Cell Efficiency through Genetic Algorithms

Pacheco M.A., Pontifical Catholic University, Rio de Janeiro, BR

In this work, a study of quantum well solar cells (QWSCs) is carried through. The use of quantum wells was pointed as a tool to increase the efficiency of photovoltaic. The objective is to describe [...]

Controllable Electron Transport in the Lateral Nanostructure

Pogrebnyak V.A., Akray E., Küçükaltun A.N., Cukurova University, TR

The study of two-dimensional electronic systems evokes considerable interest due to the broad utilization of the systems in nanotechnology. Design of new devices are commonly based on exploiting the different configurations of multiple-quantum-well (MQW) structures. [...]

Squeezed Electrons in GaN Quantum Wells

Ridley B.K., Zakhleniuk N.A., Bennett C.R., University of Essex, UK

We present an analytic theory of hot-electron transport in a GaN quantum well containing a large-enough electron concentration for strong electron-electron scattering to establish a drifted distribution. Novel behaviour includes the squeezed electron distribution and [...]
