Effect of thermal environment evolution on AlN bulk sublimation crystal growth

Growth of bulk AlN single crystals with low oxygen content taking into account thermal and kinetic effects of oxygen-related gaseous species

“…Due to modification of our graphite based growth set-up and changing of the growth procedure, we have grown seeded and spontaneously nucleated isometric AlN crystals in partially opened tungsten crucibles under similar growth conditions (temperatures and temperature gradients) as reported earlier [19][20][21]. In the case of seeded AlN crystals, we investigated the impurity incorporation during single crystal growth.…”

Pseudohalide vapour growth of thick GaN layers

“…Cai et al [21] speculate the degradation of the graphite parts in their AlN sublimation equipment due to the formation of ''carbon nitride…”

Numerical study of radial temperature distribution in the AlN sublimation growth system

“…At such temperature, it is not feasible to directly monitor the growth process. Therefore many efforts have been done to understand the growth system through theoretical modeling and simulation and a lot of useful results were obtained, such as the AlN growth rate, the temperature distribution in the crucible and the thermal stress distribution in the as‐grown crystal.…”
