thermal pulse method

thermal pulse method

[′thər·məl ¦pəls ‚meth·əd]
(solid-state physics)
A method of measuring properties of insulating and conducting crystals, in which a heat pulse of known duration is measured after propagating through a crystal; the pulse can be generated by directing a laser pulse at an absorbing film evaporated onto one face of the crystal, and detected by a thin-film circuit on the other face.
