Investigation of Energy and Density of Laser-Ablated Si and Ge Plasma Ions Along With Surface Modifications
Autor: Khaliq Mahmood, Asma Hayat, Fida Hussain, Shazia Bashir, Amna Batool, Haroon Ahmad
Publikováno v: IEEE Transactions on Plasma Science. 48:4191-4203
The energy and density of laser-generated Si and Ge plasma ions have been investigated by using Faraday cup (FC). Nd: YAG laser (532 nm, 6 ns) at different irradiances ranging from 4 to 7.1 GWcm−2 has been employed as an irradiation source. FC meas

The Irradiance-Based Growth of Surface Structures Induced by Nanosecond Laser Pulses on Si and Ge and Their Correlation With Plasma Ion Kinetic Energies and Densities
Autor: Haroon Ahmad, Shazia Bashir, Asma Hayat, Khaliq Mahmood, Ghulam Ghous
Publikováno v: Journal of Micro and Nano-Manufacturing. 10
The laser irradiance-based surface structural growth on Si and Ge has been correlated first time with plasma parameters. The better control over plasma parameters makes manufacturing of various sized and shaped surface structures on the semiconductin
