Hi Anwar:

For bulky silicon, the poisson's ratio is 0.22 - 0.27, thermal conductivity 1.3
W cm-1°C-1, Thermal expansion coefficient 2.6·10-6°C -1. Cannot find the value
of Jeta.

You may refer to http://www.memsnet.org/material/siliconsibulk/ and

semiconductor manufacturers I worked in we alloyed aluminum to silicon at about
435 degree C in a reducing atmosphere. It led to the manufacture of our 450
