Optical interference effect of a thick absorbing LT-GaAs layer on a Bragg reflector
Near-infrared reflectance spectra of 5 μm thick low-temperature (LT) GaAs films on GaAs/AlAs Bragg reflectors (BRs) have been studied by model calculations as a function of the linear absorption coefficient of the films αf. [...]
What is silicon made of?
Silicon is made from silicon dioxide, or silica – found in nature as quartz, or common beach sand.
First, the silica is put into a Silicon Furnace, where a carbon electrical arc reacts at high temperatures to drive the oxygen out [...]
PAM XIAMEN offers Single crystal CdWO4.
CdWO4 is an excellent scintillating crystal for X-Ray detection. Its high light output enables to make a compact detector module by coupling efficiently with the spectral response of silicon photodiodes.

Towards the cost effective epitaxy of hillocks free CdZnTe film on (001)GaAs by close-spaced sublimation
Cost-effective epitaxy of hillocks free CdZnTe films on (001)GaAs was explored with close-spaced sublimation (CSS) technique. The orientation and film quality were studied with scanning electron microscopy (SEM), X-ray diffraction θ–2θ and Φ scans [...]
