摘要：

In a study of the properties of composite cryogenic bolometers using an amorphous metal-semiconductor thin him as sensor, we have deduced the NbSi Anderson insulator specific heat. The results are model-dependant, but agree with those obtained by direct measurements. The behavior observed for NbSi is identical to that found for Si:P, suggesting that it is universal for Anderson insulators. (C) 1999 Elsevier Science B.V. All rights reserved.
