“…This seeming contradiction must be explained on the basis of the applicability range of Klosse's model [23]. As already pointed out elsewhere [24], with iodine concentrations below certain values, the transport rate is likely to be governed by the rate of heterogeneous reaction of source vaporisation, rather than by diffusion, regardless of the temperature gradient applied. We believe that this is most probably the case for test No.…”

“…The interested reader is referred to Klosse's work [23] for a detailed treatment of such aspects. For example, for simple systems it is known that crystallographic perfection is favoured under diffusion-limited transport rate, when nucleation density is minimized [24]. However, due to the pentanary nature of our system, the formation of compositionally well-defined sinks is subject to the risk of incongruent transport [33].…”

“…CVT-grown ZnSe crystals contain iodine and have strong SA emission, which is favorable for white LED fabrication. However, it is difficult to grow large-diameter ZnSe single crystals by the CVT method, since convective mass transport deteriorates the stability of surface morphology [7]. Several years ago, rotational CVT (R-CVT), which comprises the rotation of the horizontal growth ampoule with a constant frequency, was developed to facilitate the growth of 1 in.…”

“…7, and could be caused possibly by thermal convection [19,23,28,30,33,50,53,57,65,81]. Upon opening the ampoule in that case, the total pressure at room temperature appeared to be higher than one bar by reason of unknown vapor.…”
