Growth of high-quality ZnO single crystals by seeded CVT using the newly designed ampoule

Chemically assisted vapour transport for bulk ZnO crystal growth

“…Other possible CVT methods were proposed by Udono et al [20]and Mikami et al [21],who used PVA organic compound as carbon source. Similar experiments were carried out by Hong et al [22] and Wei et al [23].…”

Growth Measures to Achieve Bulk Single Crystals of Transparent Semiconducting and Conducting Oxides

“…For example, variants of the CVT method include the cold-wall CVT by Abe et al [42], contactless CVT by Grasza et al [43], and seeded CVT by Hong et al [89]. For example, variants of the CVT method include the cold-wall CVT by Abe et al [42], contactless CVT by Grasza et al [43], and seeded CVT by Hong et al [89].…”

“…The transport agents used in this growth method included H 2 [90], C [89,91], CO 2 þ Zn [92], [42], C þ CH 4 [45], C þ Cl [46], and many others (see e.g., Ref. The crystallinity of the CVT-grown ZnO can be very good, as 30 and 44 arcsec of the FWHM of the rocking curves were reported [46,89]. Typically, quartz or graphite-covered quartz ampoules are used; the source temperature is smaller than 1200 C and the crystallization takes place in the cooler region of the ampoule (e.g., by about 50 K).…”

Seeded growth of high-quality transition metal dichalcogenide single crystals via chemical vapor transport

“…Adding a seed crystal at the deposition end could prevent such unwanted nucleation and significantly improve the crystal growth. To this far, seeded growth in CVT are mainly reported on the growth of ZnO and Cu 2 OSeO 3 bulk crystal, [36][37][38][39] while its attempt in TMD crystal growth is yet to be explored.…”
