In situ measurement of Bi4Ge3O12 interface supercooling during melt crystal growth

Feasibility study of cadmium zinc telluride growth using a submerged heater in a vertical bridgman system

“…Contemporaneously with the development of the SHM, Golyshev and co-workers developed the closely related AHP method. [16][17][18][19][20] The AHP method has much in common with SHM and generally produces the same benefits, but differs somewhat in design and practice. As the name implies, the authors characterize it somewhat more abstractly, in terms of controlling the thermal field rather than in terms of the heater geometry.…”

“…Adding a submerged heater to the vertical Bridgman configuration in the manner of the submerged heater method (SHM) [10][11][12][13][14][15] and axial-heat-flux-closeto-the-phase-interface (AHP) [16][17][18][19][20] systems are proposed to overcome these problems. A typical system is illustrated in Fig.…”

Industrial challenges for numerical simulation of crystal growth

“…An interface undercooling could be large (for example, up to 20 K in bismuth germanate growth [22]). It is usually claimed that the facetting is harmful for crystal quality [41] and thus should be avoided by keeping thermal gradient above a critical value.…”

Industrial Challenges for Numerical Simulation of Crystal Growth

“…In the latter case melt/crystal boundary does not follow the melting point isotherm, but coinsides with a crystallographic plane. Interface undercooling could be large (for example, up to 20 K in bismuth germanate growth [10]). It is usually claimed that the facetting is harmful for crystal quality [29] and thus should be avoided by keeping thermal gradient above a critical value.…”
