Physical principles of creation of new elements of optically-electronic devices on a base mono- and nanoсrystallical silicon carbide

Physical and technological problems of creation of optical radiators and photodetectors, which use the phenomenon of electrical breakdown for its application in optical-electronic devices, are investigated. The usage of silicon carbide with its super-unique properties allows to solve the actual problem of creating of radiation stable, high temperature element basis for the systems of atomic industry, nuclear energy, military and space techniques.

The size effects in the structures based on silicon carbide

1  світлодіодний імітатор випромінювання зірок; 2  еталонний широкосмуговий випромінювач на діапазон 250700 нм; 3  імпульсний випромінювач з радіатором; 4  імпульсний випромінювач.

Conditions for creation of light emitting diodes working in electrical breakdown regime have been determined. The floatable technology have been used. Light emitting diodes obtained is possible to use as standards of power and spectral composition of radiation, and although for creation of sources of short light impulses. Constructions of these devices, laboratorial technology of their fabrication, elements of metrological support have been worked out.
Emitters on SiC-basis operating in the electrical breakdown regime have the following superior characteristics:
