Starting from the conjecture that future large-scale neurom... » read more

Substitutional synthesis of sub-nanometer InGaN/GaN quantum wells with high indium content

Abstract "InGaN/GaN quantum wells (QWs) with sub-nanometer thickness can be employed in short-period superlattices for bandgap engineering of efficient optoelectronic devices, as well as for exploiting topological insulator behavior in III-nitride semiconductors. However, it had been argued that the highest indium content in such ultra-thin QWs is kinetically limited to a maximum of 33%, narro... » read more
