Uncovering a Vital Band Gap Mechanism of Pnictides

Advanced Science, 2022
Pnictides are superior infrared (IR) nonlinear optical (NLO) material candidates, but the exploration of NLO pnictides is still tardy due to lack of rational material design strategies.

Twinning superlattices in indium phosphide nanowires [PDF]

, 2008
Here, we show that we control the crystal structure of indium phosphide (InP) nanowires by impurity dopants. We have found that zinc decreases the activation barrier for 2D nucleation growth of zinc-blende InP and therefore promotes the InP nanowires to ...
