Crystal Growth in Substrate-Confined Liquids
Abstract
The task objective was to develop crystal growth techniques utilizing substrate-confined-liquids (S.C.L.). In particular, crystals were usually grown as arrays of single crystals and include semiconductors useful as detectors. The primary technical problem remaining at this time was to extend techniques for growing a single crystal at each location in the array to include semiconductors useful in photodetection. The basic approach was experimental, utilizing a laboratory already equipped for vacuum evaporation and C.V.D. with analysis largely by optical, x-ray, and SEM techniques. The main result obtained so far was that arrays of In single crystals can be grown with a common basal plane orientation: (101) parallel to substrate surface. These crystals exhibited facets on their upper surfaces closely parallel to the substrate surface. Also cleaning procedures were developed for the In, which should be useful for In compounds as well. The main importance of this result is the possibility of carrying it over to the useful detector materials, InSb and CdTe. Based on various earlier findings, there appears to be a fair probability that stoichiometric growth of such semiconductors should occur similarly to that of In noted above.
