Crystal growth of quantum materials: a review of selective materials and techniques

Availability of quantum materials as sufficiently large and high-quality single crystals holds the key to understanding their physical properties, which is crucial for making future progress in this exciting area of research. Here we review the crystal growth of a few representative quantum materials of topical interest grown in our laboratory using various crystal growth techniques, including optical floating zone, traveling solvent floating zone, chemical vapour transport and high-temperature flux methods. The chosen materials classes include: (a) low-dimensional quantum magnets, (b) superconductors of the pnictide family, (c) layered materials with triangular and honeycomb lattices and (d) 2D transition-metal based chalcogenides. Their quintessential physical properties demonstrating quantum behaviour are also shown in some cases.
