Pure silicon is more like an insulator than a conductor, and when external forces are applied (such as applied voltage), it has no ability to change its conductive state. So other elements must be doped into silicon, and the two most important dopants are boron (B) and [...]

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 [...]
Gallium Nitride (GaN) is the basic material of blue LED and has important applications in LED and ultraviolet laser.
PAM-XIAMEN can epitaxially grow GaN wafers for LED and LD. For more wafer specification please visit:https://www.powerwaywafer.com/gan-wafer/epitaxial-wafer.html. How do we grow GaN LED epiwafer on sapphire?

Experimental and theoretical investigation of phosphorus in-situ doping of germanium epitaxial layers
We investigate phosphorus in-situ doping characteristics in germanium (Ge) during epitaxial growth by spreading resistance profiling analysis. In addition, we present an accurate model for the kinetics of the diffusion in the in-situ [...]
PAM-XIAMEN can supply semiconductor wafers, more wafer specifications please refer to https://www.powerwaywafer.com/products.html. If necessary, we will offer PL (photoluminescence) spectroscopy for the semiconductor wafers.
1. What is PL?
About PL, it refers to the self-emission light produced by a material after being excited by light. When [...]
