Abstract:

The objectives of this task is to develop crystal growth techniques utilizing substrate-confined-liquids S.C.L.. In particular, the crystals will mostly be grown as arrays of single crystals and will include semiconductor crystals useful as detectors. The primary technical problem is to learn how to produce stable arrays of pools of liquid in the substrate surface S.C.L. and to grow a single crystal from each liquid pool. The approach to the problem is primarily experimental. A classical theoretical framework already exists to guide the experiments, which now must test a number of parameters to optimize stability and crystal growth. Some results have been obtained with germanium and are treated in the next section of this report. An important finding at this time is that, at least under some conditions, germanium appears to nucleate within the fluid phases rather than at the substrateliquid interface. The implication of this for further research is that there is a possibility of align crystals grown from S.C.L. Most hardware development at this time has to do with pattern design for the substrates and the subsequent processing of the substrates.
