Ab initio calculations show that a transverse electric field induces a homojunction across the diameter of initially semiconducting GaN single-crystal nanotubes (SCNTs) and nanowires (NWs). The homojunction arises due to the decreased energy of the electronic states in the higher potential region wi…
