(Editor's Feature) A Hole Flatland :
When two distinct materials are placed on top of each other, the difference in polarization between the two layers can induce charge carriers at the interface. Many such two-dimensional (2D) electron gases have been observed, but engineering a 2D hole gas without the help of doping has been much trickier. Chaudhuri et al. used molecular beam epitaxy to grow a layer of gallium nitride on top of aluminum nitride without introducing dopants. This approach resulted in a high-density 2D hole gas at the interface in this technologically relevant system.

A study of the growth conditions during molecular beam epitaxy (MBE) growth of metal‐polar GaN/AlN heterostructures is presented for optimal transport of the polarization‐induced 2D hole gases (2DHGs), along with the demonstration of large‐area growths of the 2DHGs on 2 in. wafers using optimized growth conditions.
