We observed Shubnikov–de Haas oscillation and the quantum Hall effect in a high-mobility two-dimensional electron gas in polar ZnO/Mg x Zn 1– x O heterostructures grown by laser molecular beam epitaxy. The electron density could be controlled in a range of 0.7 × 10 12 to 3.7 × 10 12 per square centi...
