(a) The schematic of the fabricated ZnO device. Two-dimensional electron gas is formed between (Mg, Zn)O and ZnO. Quantum dots are formed by applying gate voltage to this two-dimensional electron gas. (b) Scanning electron microscope image of the device. The triple quantum dots are formed in the lower half, and the sensor quantum dot and quantum point contact are formed in upper half.
