Temperature effects on bonds
WebIncreases in temperature reduce the bandgap of a semiconductor, thereby effecting most of the semiconductor material parameters. The decrease in the band gap of a semiconductor with increasing temperature can be viewed as increasing the energy of the electrons in the material. Lower energy is therefore needed to break the bond. WebIn the study of combustion, the adiabatic flame temperature is the temperature reached …
