Graphene-quantum dot hybrid optoelectronics at visible wavelengths

Salihoğlu, Ömer; Kakenov, Nurbek; Balcı, Osman; Balcı, Sinan; Kocabaş, Çoşkun (American Chemical Society, 2018-06)

With exceptional electronic and gate-tunable optical properties, graphene provides new possibilities for active nanophotonic devices. Requirements of very large carrier density modulation, however, limit the operation of ...
Stable monolayer α-phase of CdTe: Strain-dependent properties

Ünsal, Elif; Senger, Ramazan Tuğrul; Şahin, Hasan (Royal Society of Chemistry, 2017)

CdTe is a well known and widely used binary compound for optoelectronic applications. In this study, we propose the thinnest, free standing monolayer of CdTe which has a tetragonal-PbO (α-PbO) symmetry. The structural, ...
