More To Come
In September, 2020, Meylor Global CEO Yuliya Kusher commented on these type IIb crystals and the company’s larger goals.
The semiconducting properties of our large type IIb diamond stones, specifically intended to produce the single sector diamond plates ((111) or 100) orientations, will greatly facilitate the development of diamond based electronics by boosting the related research with CVD methods diamond layers overgrowth… The significant milestone of 100ct+ size in diamond size was achieved by our company in a very short time and the next even more promising target of 200 ct+ is right now under deep scientific investigation.
