, 2011 We calculated the phonon dispersion relations of ZnX (X=Se, Te) employing ab initio techniques. These relations have been used to evaluate the temperature dependence of the respective specific heats of crystals with varied isotopic compositions.

Photon emission induced by elastic exciton--carrier scattering in semiconductor quantum wells [PDF]
, 2008 We present a study of the elastic exciton--electron ($X-e^-$) and exciton--hole ($X-h$) scattering processes in semiconductor quantum wells, including fermion exchange effects.

Synthesis of Novel Stable ZnSe Magic‐Sized Clusters and Their Direct Transformation to Quantum Dots
Advanced Science, EarlyView.We have developed a low‐temperature synthetic approach that enables the fabrication of novel ZnSe MSCs with remarkable thermal stability. These stabilized MSCs serve as efficient precursors that can be readily converted to ZnSe QDs under mild conditions through simple introduction of a selenium source.

Femtosecond laser induced nano-meter size surface structures on ZnSe film
AIP Advances, 2019 We realize femtosecond laser-induced high spatial frequency nano-meter size periodic surface structures with a periodicity about 140nm-170 nm on ZnSe film in one step.

High quality epitaxial ZnSe and the relationship between electron mobility and photoluminescence characteristics [PDF]
, 1989 High quality epitaxial layers of nominally undoped ZnSe have been grown by metalorganic chemical vapor deposition at low temperature (325 °C) and pressure (30 Torr), using dimethylzinc and hydrogen selenide.

Ultrafast Carrier Dynamics in Type II ZnSe/CdS/ZnSe Nanobarbells
ACS Nano, 2010 We employ femtosecond transient absorption spectroscopy to get an insight into ultrafast processes occurring at the interface of type II ZnSe/CdS heterostructured nanocrystals fabricated via colloidal routes and comprising a barbell-like arrangement of ZnSe tips and CdS nanorods.
