The proposal project belong to category of Applied Research. The general goal of the project is determination of the materials, design and technology that provide possibility to manufacture extremely sensitive Josephson devices based on metaloxide superconductors with high-critical temperature for detection of weak electromagnetic radiation in a wide frequency range.

Project objectives

The activity in the frame of the project can be divided into 5 main tasks:

• Design, fabrication and testing of MOS Josephson junction for submm wave detecting.

• Design, fabrication and testing of MOS SQUID system for biomagnetic applications and non-destructive tests of integrity of metallic parts of crucial constructions at Hz frequencies.

• Simulation, design, and fabrication of devices based on both MOS SQUID and MOS multijunction structure for the signal amplification at GHz frequencies.

• Development of bicrystal design and fabrication technique of novel Josephson junctions with the tilt-type grain boundary.

• Fabrication and test of both MOS–normal metal and MOS–metallic superconductor heterostructures suitable for the hybrid microelectronic circuits.
