With the increasing development of semiconductor devices, silicon and silicon-based materials still show their superior properties, and it will still be an important material for semiconductor devices and integrated circuits. With the decreasing size of devices, the resistivity, impurity distribution, film thickness and quality [...]

Phosphorus-containing III-V compounds are the preferred materials for millimeter-wave and submillimeter-wave devices and circuits, optoelectronic devices, and solar cells. InGaP lattice matched to GaAs has a direct band gap of 1.9eV at room temperature, which is a highly efficient light-emitting material. We are pleased [...]

Carbon neutrality refers to through afforestation, energy saving and emission reduction, etc., to offset the carbon dioxide or greenhouse gas emissions generated by itself, to achieve positive and negative offset, to achieve relatively “zero emissions”. Only by reducing energy consumption can carbon emissions be [...]

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 [...]
Highlights
