Using all-atom molecular dynamics simulation, we have studied the effect of size and
temperature on the strain induced phase transition of wurtzite CdSe nanowires. The wurtzite
structure transforms into a five-fold coordinated structure under uniaxial strain along the c
axis. Our results show that lower temperature and smaller size of the nanowires stabilize the
five-fold coordinated phase which is not a stable structure in bulk CdSe. High reversibility of
this transformation with a very small heat loss will make these nanowires suitable for …
