Title: Fabrication of single crystal architecture in Sb-S-I glass: Transition from dot to line

Abstract

We have investigated the occurrence of the sometimes observed grain boundaries, as initial seed is extended to form line in laser-fabricated single-crystal architecture in glass (SCAG). In particular, for Sb2S3 SCAG in Sb-S-I glass as a model system, grain boundaries are formed during the transition from laser-written initial seed dot to crystal line. Such grain boundaries during the growth of Sb2S3 crystals occur in 16SbI3-84Sb2S3glass, whereas they are absent in Sb2S3 glass. We correlate this difference in tendency to form multiple grains with the relative glass forming ability i.e. the dynamics of nucleation and crystal growth as determined by differential scanning calorimetry (DSC). On the basis of this understanding, methods to minimize the appearance of grain boundaries in the transition region are suggested.

Figure-1 Figure-1: Sb2S3 SCAG consisting of initial dot and subsequent line on the surface of 16SbI3–84Sb2S3 glass: SEM image (a), image quality (IQ) (b), colored inverse pole figure (IPF) map with reference vector normal to sample surface (ND) (c) and crystal orientation deviation (COD) map (d). The crystal dot was createdmore » by slowly ramping in 5 s the power density from 0 to 90 μW/μm2 and then constant power exposure for 60 s. It was subsequently transformed to a crystal line by moving the laser spot at a scanning speed 20 μm/s in nitrogen environment for a distance of 75 μm. Scale bar corresponds to 5 μm.« less
