What is it about?
It is about a very attractive material, an III-V alloy containing Bi. It can be used in optoelectronics and spintronic.

Why is it important?
The introduction of Bi into III-V alloys changes the material and results in a band-gap reduction and spin-orbit splitting. The incorporation of the Bi atoms into III-V alloys is very challenging..
Perspectives
It has great potential for near-to-mid infrared optoelectronics applications because of the large bandgap reduction. It can help in the interpretation of GaBi-related Raman peaks. It includes the resonant Raman effect and polarized Raman spectroscopy.
