Abstract
The time-dependent specific heat of amorphous Si has been measured between 0.1 and 1 K over the range ∼ 1 sec to 10 μsec. The decoupling of the roughly -dependent contribution to specific heat is observed in submillisecond time scales, in qualitative agreement with the predictions of the tunneling model. However, the excess -dependent specific heat is not decoupled on the time scales involved.
