Purpose of the development: For use in industry, medicine, environmental protection.

Recommended application field: Medicine, ecology, different branches of production.

Technical characteristic: The main technical and economic characteristics of the development: Name and unit value indices developed object Structure of Au / GaAs Au metal working Thickness of 45 nm Polarization sensitivity, IP / IS> 3:1 The half-width of the resonance maximum 1.77 degrees. Fixed limit of sensitivity index refractive index of the environment, is not a sign of det. 0.00016

Advantages over analogues: Compared with other sensors on the basis of this SPR sensor has the following advantages: - Using the same structure as for the excitation of SPR and for its registration, resulting in mechanical scanning system, if it is needed, it becomes easier; - Compact and related low materials per unit of output (eg, gold content); - The theoretical possibility of its production on a large scale by means of the microelectronics industry.

The development stage readiness: Ready for application

Description of the development:
()
The sensing element is a photodetector based on the Schottky barrier (Au / GaAs) mikroprofilirovannoy with the interface - the metal / semiconductor interface. Physics of the sensitive element of the sensor is to excite surface plasmon waves ( surface plasmon polariton ( PE ) on the interface - air / metal. Application element is to find the angle at which the PP is excited and the maximum of the photocurrent. Next, using a calibration dependencies can determine the angle or wavelength of incidence or polarization. Thus , it is possible to determine the refractive index of the contacting medium. There is also another more simplified measurement technique .
