Properties of InGaN blue laser diodes grown on bulk GaN substrates
High-pressure growth from solution is at present the only method able to provide true bulk GaN monocrystals. In this paper, we would like to demonstrate that in spite of their small, centimeter range size, [...]
By analyzing the MOSFET, it is known that the switch can be realized by controlling the change of the PN junction.

PAM XIAMEN offers MoSe2 crystal.
MoSe2 is a layered material with strong in-plane bonding and weak out-of-plane interactions. These interactions lead to exfoliation into two-dimensional layers of single unit cell thickness. In addition, MoSe2 have sizable bandgaps that change from indirect to direct in [...]
