METHOD OF DETECTING ELECTROMAGNETIC RADIATION AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2013 - IPC H01L31/101 H01L27/14 

FIELD: physics.

SUBSTANCE: method involves generating reference emf via spatial separation of charges arising from irradiation of structures made of semiconductor materials and including a potential barrier and an array of quantum-size objects in the region of the barrier with radiation with particle energy in the region of fundamental absorption in structures or during injection of charge carriers through the potential barrier as a result of irradiation of such structures with radiation with particle energy sufficient for injection of charge carriers, irradiation of quantum-size objects with detectable electromagnetic radiation, recording change in emf when the structures are irradiated with detectable electromagnetic radiation. Said result is achieved due to that the device has structures made of semiconductor materials having a potential barrier in the region of which an array of quantum-size objects is formed, a reference radiation source for irradiating structures in order to generate reference emf and a device which detects change in emf when the device is irradiated with detectable electromagnetic radiation.

EFFECT: high sensitivity and providing optical control of characteristics of a photovoltaic detector, particularly dynamic range and sensitivity.
