Document Summary
At room temp, many donor e- are promoted. Position of donor state is a function of both temp and donor concentration doped, adds e-, # e- >>> # holes, e- majority, holes (cid:373)i(cid:374)orit(cid:455), (cid:862)do(cid:374)or (cid:373)aterial(cid:863) = gi(cid:448)es e. Heat capacity measures energy content of a material. Amount of nrg required to produce a unit temperature rise. Needs to measured at constant pressure or constant volume. Vibrational heat capacity in solid materials atoms are always vibrating at high frequencies and small amplitudes many traveling lattice waves are produces. **at high temperatures the behaviour of materials become intrinsic. Thermal conductivity a material property that is indicative of the extent to which a material expands upon heating and has units of reciprocal. If you want to open a jar lid you would put it under hot water to make the metal expand, but if it is a plastic lid you would want to freeze it.
