Abstract : Thermoelectric cooling under non-steady state conditions established by repeated square current pulses was studied. A qualitative agreement was found for p-type Bi2Te3 between the experimental results and the phonon drag theory which predicts a gain in non-steady state thermoelectric cooling over equivalent direct current steady state cooling. It was found that 0.1 and 0.3 sec pulse cycles caused the largest gain in delta T and that this gain was accompanied by an even larger gain in the coefficient of performance of the cooling junction.
