Pulsed Laser Annealing for Diamond Doping

Description:

This innovative method uses pulsed laser annealing (PLA) to incorporate and activate dopants in diamond thin films by first depositing a dopant precursor layer on the diamond surface and then applying targeted laser pulses. The process improves doping precision while reducing thermal damage compared to conventional techniques. Experimental validation using X-ray Photoelectron Spectroscopy and Hall Effect Measurements confirms enhanced electrical properties of the doped diamond. Though in early development, the technique promises advanced control over diamond doping for semiconductor applications.
