摘要：
This works presents a study of the location of 3D band-to-band tunneling barriers in order to create improved tunneling devices. Specifically, the i-Si / n-InAs junction is considered. The large lattice mismatch in this material system causes dislocations in the interface and traps in the bandgap. Alternative device configurations are considered that move the tunneling away from the physical interface, therefore reducing the the effects of lattice mismatch on tunneling current.
