Large-area femtosecond laser milling of silicon employing trench analysis

Arun Bhaskar, Justine Philippe, Flavie Braud, Etienne Okada, Vanessa Avramovic, Jean-François Robillard, Cédric Durand, Daniel Gloria, Christophe Gaquière, Emmanuel Dubois

A femtosecond laser is a powerful tool for micromachining of silicon. In this work, large-area laser ablation of crystalline silicon is comprehensively studied using a laser source of pulse width 300 fs at two wavelengths of 343 nm and 1030 nm. We develop a unique approach to gain insight into the…

Dielectric Passivation and Edge Effects in Planar GaN Schottky Barrier Diodes

B. Orfao, B. Vasallo, S. Perez, J. Mateos, D. Moro-Melgar, M. Zaknoune, T. Gonzalez

The influence of passivation on the edge effects (EEs) present in the capacitance-voltage ( C- V) characteristics of GaN Schottky barrier diodes (SBDs) with realistic geometry is analyzed by means of Monte Carlo simulations. The enhancement of the performance of SBDs as frequency multipliers is…

Piezoresistance in defect-engineered silicon

Heng Li, Abel Thayil, Chris Lew, Marcel Filoche, Brett Johnson, Jeff Mccallum, S. Arscott, Alistair C. H. Rowe

The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a function of applied bias. Above a punch-through voltage (Vt) corresponding to the onset of a space-charge-limited hole current…
