At absolute zero, semiconductors behave like insulators because no electrons have enough energy to cross the band gap. However, at room temperature or higher, thermal energy excites some electrons ...

“This finding not only explains why certain organic semiconductors exhibit an unusually low temperature dependence of their thermal conductivity, but also enables a more targeted design of materials ...

Silicon is the best-known semiconductor material ... technique optimised at HZB and determined the temperature-dependent electrical conductivity and thermopower. Electrons in wavelike states ...

The study covered the frequency range between 0.1 to 20 kHz at temperatures in the range 150 to 430 KIn this temperature range it is expected to have only one phase (α-form). It was, however, observed ...

A step forward in the development of diamond CMOS integrated circuits. A research team at NIMS has developed the world’s ...
