Purpose of the development: Fotovarikap designed as a functional element for the monitoring and control of the environment, communications, process automation and control.

Recommended application field: Development can be realized on the enterprises of the Ministry of engineering, instrumentation, єkologii, MES and others.

Technical characteristic: Main technical characteristics: - The range of the wavelength of light, MKM 0.8-2.5; - Consumer power, mW, not more than 10; - Specific capacity, pF / cm sq. (30-90) [3.10]; - Basic error, not more than 0.5%; - Overall dimensions 2x2x1.

Advantages over analogues: An analysis is made on the basis of patent search shows that fotovarikap with pyroelectric has several advantages over similar products. In particular, the use as dielectric pyroelectricity allows more than 10-fold increase in the photosensitivity of the device.

The development stage readiness: tested in laboratory condition

Technical and economic effect: The economic attractiveness of MDN - fotovarikapa based on the use of common technologies of microelectronics group, low labor intensity. Estimated cost of one element with serial production of 1000 pieces per year reserves of $ 10, which is significantly less than the cost of the analogs. Technical and economic parameters are allowed to use the sensor for a wide range of measuring equipment.

Description of the development:
()
Fotovarikap have sensitive to light elements on the basis of structures of metal - insulator - semiconductor. Dielectric, unlike common compounds (Sі2, Sі3N4) is pyroelectric, for example, a solid solution SrxBa1-x Nb2O6 (x = 0.08-0.12). When illuminated by the beam structure is partially absorbed in the pyroelectric, partly in the semiconductor. On the layer surface tension arises Pyro whose sign opposite to the sign of the applied bias. In the capacitance change MDN elementa illuminated added contribution photo effects in the semiconductor and pyroelectric. Both of these processes are mutually stimulate each other. Fotovarikap designed as a functional element for the monitoring and control of the environment, communications, process automation and control. A test of the elements in the composition of industrial equipment optoelectronics devices.
