FIELD: physics.
SUBSTANCE: method of controlling light sensitivity of a laser radiation detector in the infrared range by exposing the detector to external fields, for a detector made from quantum wire based on InSb, doped with a donor-type impurity, with quantum wire diametre approximately equal to the value of the effective Bohr radius for an electron in the material of the quantum wire. The external effect is magnetic field with induction between 2 and 5 T.
EFFECT: broader light sensitivity of the laser radiation detector in the submillimetre wavelength range.
