Abstract :
AlInAs/GaInAs double barrier resonant tunnelling structures have been grown by metal-organic chemical vapour deposition and show peak/valley current ratios as high as 3.3:1 at 293 K and 15.3:1 at 77 K. The devices also exhibit current bistability similar to that observed in other materials systems
