Spectroscopic investigation of quantum confinement effects in ion implanted silicon-on-sapphire films
Rajesh Kumar, H. S. Mavi, A. K. Shukla
Crystalline Silicon-on-Sapphire (SOS) films were implanted with boron (B) and phosphorous (P) ions. Different samples, prepared by varying the ion dose in the range $10^{14…

Thermal effects on electron-phonon interaction in silicon nanostructures
Rajesh Kumar, Vivek Kumar, A. K. Shukla
Raman spectra from silicon nanostructures, recorded using excitation laser power density of 1.0 kW/cm^2, is employed here to reveal the dominance of thermal effects at temperatures…
