Characterization of Traps in GaN pn Junctions Grown by MOCVD on GaN Substrate Using Deep-Level Transient Spectroscopy
Minority- and majority-carrier traps were studied in GaN pn junctions grown homoepitaxially by MOCVD on n+ GaN substrates. Two majority-carrier traps (MA1,MA2) and three minority-carrier traps (MI1, MI2, [...]

6″CZ Prime Silicon Wafer-3
PAM XIAMEN offers 6″CZ Prime Silicon Wafer with orientation (111)
In materials science, when discussing the growth of crystals, the position of atoms in crystals, the direction of atomic rows and the plane of atoms are often involved. We call the crystal [...]

PAM XIAMEN offers Yb YAG Ytterbium (Yb) doped Yttrium Aluminium Garnet Laser Crystal.
Ytterbium – Yb:YAG is a very promising laser crystal and is more suitable for diode-pumping than the commonly used Nd-doped YAG crystals. Compared with the traditional Nd:YAG crystal, Yb:YAG crystal has a much wider [...]

Photoluminescence-based material quality diagnostics in the manufacturing of CdZnTe ionizing radiation sensors
A photoluminescence method was used for characterization of crystalline perfection of CdZnTe single crystals in the different stages of an up-to-date process of ionizing radiation sensor production. It was shown that the point [...]
Highlights
•MOCVD growth of a p-GaN/i-InGaN/n-GaN (PIN) solar cell on ZnO/Sapphire templates.
•In-depth structural characterizations showing no back-etching of ZnO.
•Chemical lift-off and wafer-bonding of the structure on float glass.
•Structural characterizations of the device on glass.
Abstract
p-GaN/i-InGaN/n-GaN (PIN) structures were grown epitaxially on ZnO-buffered c-sapphire substrates by metal [...]
