Current transport in semiconductor nanowires with built-in barriers based on a 1D transfer matrix calculation
Zervos, Matthew; Pelekanos, N. T. (2008)A one dimensional (1D) transfer matrix calculation of current transport in semiconductor nanowires with built-in barriers is described within the effective mass approximation by taking into account (i) the quantum confinement ...

InAs quantum dots grown by molecular beam epitaxy on GaAs (211)B polar substrates
Zervos, Matthew; Xenogianni, C.; Deligeorgis, G.; Androulidaki, M.; Savvidis, P. G.; Hatzopoulos, Z.; Pelekanos, N. T. (2006)InAs nanostructures were grown by molecular beam epitaxy on GaAs (211)B at temperatures between 400-530 °C and growth rates that were varied between 0.1 to 0.02 mono-layers (ML) per second. For temperatures up to 500 °C ...

Influence of polarization field on the lasing properties of III-nitride quantum wells
Dialynas, G. E.; Deligeorgis, G.; Zervos, Matthew; Pelekanos, N. T. (2006)A theoretical investigation of the effect of polarization-induced fields on the optoelectronic properties of a 3 nm In0.2Ga0.8N/GaN single quantum well has been carried out via a self-consistent solution of Schrödinger-Poisson ...

Internal field effects on the lasing characteristics of InGaN/GaN quantum well lasers
Dialynas, G. E.; Deligeorgis, G.; Zervos, Matthew; Pelekanos, N. T. (2008)A theoretical investigation of Inx Ga1-x N/GaN single quantum well lasers with x in the range 0.05≤x≤0.3 is carried out via self-consistent Schrödinger-Poisson calculations in the effective mass approximation in order to ...

Residual Doping Effects on the Amplitude of Polarization-Induced Electric fields in GaN/AlGaN Quantum Wells
Simon, J.; Langer, R.; Barski, A.; Zervos, Matthew; Pelekanos, N. T. (2001)We show that residual doping and carrier distribution effects decrease the observed polarization-induced electric fields in GaN/AlGaN quantum wells and that these effects ought to be considered if we want to compare in a ...
