| 1. A semiconductor-on-insulator structure comprising first and second layers which are attached to one another either directly or through one or more intermediate layers, wherein the first layer comprises a substantially single crystal semiconductor material comprising germanium; the second layer comprises a glass or a glass-ceramic having a linear coefficient thermal of expansion (25-300° C.) which is about 61×10−7/° C. and within the range of +/−20×10−7/° C. of the linear coefficient thermal of expansion of the germanium first layer. |
