Heat generation in silicon nanometric semiconductor devices

In nano-devices the presence of very high and rapidly varying electric fields is the cause of thermal heating of the carriers and the crystal lattice. In fact, the external electric field transfers energy to the electrons and in turn to the lattice through the scattering mechanism. This self-heating process can influence significantly the electrical behaviour because the dissipated electrical e...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
