Electron ground state factor in embedded InGaAs quantum dots: An atomistic study
Mustafa Kahraman, Ceyhun Bulutay
We present atomistic computations within an empirical pseudopotential framework for the electron -shell ground state tensor of InGaAs quantum dots (QDs) embedded to host mat…
Strain dependence of photoluminescence and circular dichroism in transition metal dichalcogenides: a k.p analysis
Shahnaz Aas, Ceyhun Bulutay
Within a two-band method we analyze different types of strain for the valley optical characteristics of a freestanding monolayer MoS, MoSe, WS and WSe$_2…
Disorder-free localization around the conduction band edge of crossing and kinked silicon nanowires
Ümit Keleş, Aslı Çakan, Ceyhun Bulutay
We explore ballistic regime quantum transport characteristics of oxide-embedded crossing and kinked silicon nanowires (NWs) within a large-scale empirical pseudopotential electroni…
Nuclear magnetic resonance inverse spectra of InGaAs quantum dots: Atomistic level structural information
Ceyhun Bulutay, E. A. Chekhovich, A. I. Tartakovskii
A wealth of atomistic information is contained within a self-assembled quantum dot (QD), associated with its chemical composition and the growth history. In the presence of quadrup…
Networks of silicon nanowires: a large-scale atomistic electronic structure analysis
Ümit Keleş, Bartosz Liedke, Karl-Heinz Heinig +1
Networks of silicon nanowires possess intriguing electronic properties surpassing the predictions based on quantum confinement of individual nanowires. Employing large-scale atomis…
Quadrupolar spectra of nuclear spins in strained InGaAs quantum dots
Ceyhun Bulutay
Self-assembled quantum dots (QDs) are born out of lattice mismatched ingredients where strain plays an indispensable role. Through the electric quadrupolar coupling, strain affects…
