During this interaction there is a net exchange of energy which leads to a change in an intrinsic property of the atomic nuclei called nuclear spin. Witryna17 lis 2024 · Impurity doping is performed during the VLS growth of semiconductor NWs. In the chemical vapor deposition (CVD) method, diborane (B 2 H 6) gas and phosphine (PH 3) gas are generally used as the p-type and n-type dopant sources. The doping concentration can be controlled by adjusting the flux of the dopant gases. pool repairs phoenix az
