Relaxation of strained pseudomorphic SixGe1− x layers on He-implanted Si/δ-Si: C/Si (100) substrates

D Buca, RA Minamisawa, H Trinkaus… - Applied physics …, 2009 - pubs.aip.org
In this letter we present a method to increase the efficiency of SiGe layer relaxation by He+
ion implantation and annealing. Preferential nucleation of He platelets along a δ-impurity …

Strain‐Driven Self‐Assembling of Nano‐Voids and Formation of Core–Shell Bubbles in SiSn/Si Layers

P Gaiduk - physica status solidi (b), 2018 - Wiley Online Library
Self‐assembling of nanometer size voids in strained Sn precipitates after hot He+ ion
implantation is investigated by transmission electron microscopy (TEM). It is deduced from …

Physical studies of strained Si/SiGe heterostructures. From virtual substrates to nanodevices

RA Minamisawa - 2011 - osti.gov
During the past two decades, the decrease in intrinsic delay of MOSFETs has been driven
by the scaling of the device dimensions. The performance improvement has relied mostly in …

Irradiation-induced nano-voids in strained tin precipitates in silicon

PI Gaiduk, J Lundsgaard Hansen… - Applied Physics …, 2014 - pubs.aip.org
We report on self-assembling of spherically shaped voids in nanometer size strained Sn
precipitates after irradiation with He+ ions in different conditions. It is found that high …
