The aim of the project is to develop the technology of materials and structures for the detection of long-wave infrared radiation (8-14 μm) at elevated temperatures (> 200 K). The given spectral range is important for many applications, including military (imaging, detection of trace amounts of combat gases), civil, medical, industrial (control and diagnostics), space (observation of the Earth from space, detection of trace amounts of substances) and environmental (monitoring greenhouse gas emissions).

The subject of the project will be type-II semiconductor superlattices based on group III antimony compounds of the periodic table. This material is believed to be the successor of mercury cadmium telluride (HgCdTe), which is now widely used in infrared detection instruments.

The use of devices based on type-II superlattices will allow to produce more reliable, cheaper, lighter and energy-saving devices. The technology of antimonide superlattices allows flexibility in the design of materials and structures, however, due to the high degree of complexity, it requires high precision and control. That is why, despite the enormous progress in this field, in the last few years it has not been possible to produce devices that would work in the long-wave infrared range at elevated temperatures. Further research in this field is necessary.

In order to obtain the best materials and structures for infrared detection in the mentioned conditions, the superlattice technology will be developed and optimized. Both experimental techniques and advanced simulations will be used.
