Determination of supercooling in the presence of macrosteps on the growing facet of BGO

Antimony-doped germanium single crystals grown from the melt by the axial heat processing (AHP) technique

“…Modeling calculations and observation of crystals grown by AHP [13][14][15][16][17] showed that use of the above two equations predicts the interface position adequately. It should be emphasized that these equations are particularly applicable to the AHP system as the conductive baffle promotes axial heat transfer to the interface.…”

“…More recently, another growth technique called axial heat processing (AHP) was developed and patented to promote stable, planar crystal growth [12]. The technique has been used to grow Bi 4 Ge 3 O 12 , Li 2 B 4 O 7 and other crystals [13][14][15][16][17]. A comparable technique called the submerged heater method (SHM) was also patented [18] and is being investigated by Ostrogorski et al, who used it to grow Sn-Bi, doped Ge, and Si-Ge alloy crystals [19][20][21][22].…”

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.…”

Experimental and numerical analysis of coupled interfacial kinetics and heat transport during the axial heat flux close to the phase interface growth of BGO single crystals

“…In Ref. [3] the undercooling was recalculated taking into account the actual interface morphology resulting in a considerable, DT ¼ 12217 K, undercooling value for the (2 1 1) facet. Estimates have also shown a 4-5 K variation of undercooling along the facet [4].…”
