Outline of Final Research Achievements

We have realized topological insulator (TI)-semimetal transition in InAs/GaSb semiconductor heterostructures by applying back and front gate voltages. In addition, we have succeeded in detecting the conductance very close to the quantized value using the sample with a specialized shape and an electrode arrangement. In InAs/InGaSb heterostructures instead of GaSb, we have observed the energy gap larger than the room temperature.
