P–T–X phase equilibrium and vapor pressure scanning of non-stoichiometry in the Cd–Zn–Te system

Study of Te aggregation at the initial growth stage of CdZnTe films deposited by CSS

“…Te atoms have high trend of forming chains in the form of Te to Te 7 with the dominant species Te 2 [8,23,24]. The compound dissociation determines the partial pressure of the metallic atoms and Te species, while the balance between the adsorption and desorption of these species on the substrate determines the composition of the film.…”

“…According to the research of Greenberg's [23], a Te concentration variation of several parts in 10,000 around stoichiometry in CdZnTe solid would switch the dominant species in the gas phase. It is thus difficult to predict the dominant species in the gas evaporated from a compound source with most of the frequently involved composition analysis techniques.…”

Comparison of CdZnTe crystals grown by the Bridgman method under Te-rich and Te-stoichiometric conditions and the annealing effects

“…Detailed information of crystal growth was reported elsewhere [15]. According to expounded analysis of the thermodynamics and pressure-temperature-composition (P-T-X) phase diagram in the Cd-Zn-Te system [16], the amount of excess Te was determined and thus, over-stoichiometric CZT (Cd 1Àx Zn x Te 1+d ) crystals were initially expected.

Compositional effects accompanying near equilibrium vapour growth of solid solution crystals of the types IV‐VI and II‐VI

“…These studies may be qualified as belonging to the class of quasiequilibrium approach, which was a very good approximation of the experimental data collected for growth of CdTe-based crystals [1]. Such description proved applicable for preliminary characterization of near equilibrium evaporation-condensation of solid solutions, but an essential question remained open.…”
