A layer of indium antimonide sandwiched between layers of aluminium indium antimonide can act as a quantum well, and has recently been shown to exhibit the quantum Hall effect J. A. Alexander-Webber et al.
A layer of indium antimonide sandwiched between layers of aluminium indium antimonide can act as a quantum well. In such a heterostructure InSb/AlInSb has recently been shown to exhibit a robust quantum Hall effect J. A. Alexander-Webber et al.
