Core-level spectroscopy of Si/SiO_2 quantum wells: evidence for confined states
Pierre Carrier, Zheng-Hong Lu, M. W. Chandre Dharma-wardana +1
We present an experimental and theoretical study of the conduction states of crystalline Si films confined within amorphous SiO_2 barriers, using the Si-2p core-level excitations.…
Point defects in models of amorphous silicon and their role in structural relaxation
Cristiano L. Dias, Laurent J. Lewis, S. Roorda
We have used tight-binding molecular-dynamics simulations to investigate the role of point defects (vacancies and interstitials) on structural relaxation in amorphous silicon. Our…
Molecular-dynamics thermal annealing model of laser ablation of silicon
Patrick Lorazo, Laurent J. Lewis, Michel Meunier
A molecular-dynamics thermal annealing model is proposed to investigate the mechanisms involved in picosecond pulsed laser ablation of crystalline silicon. In accordance with the t…
Tight-binding molecular-dynamics studies of defects and disorder in covalently-bonded materials
Laurent J Lewis, Normand Mousseau
Tight-binding (TB) molecular dynamics (MD) has emerged as a powerful method for investigating the atomic-scale structure of materials --- in particular the interplay between struct…
