The key aims and objectives of this research project is the design, fabrication and testing of novel tunnelling device called the Asymmetrical Spacer Layer Tunnel Diode (ASPAT).

The work will investigate the performances of fully integrated Antenna-ASPAT-Matching circuits for zero bias operation from frequencies ranging from 5.8GHz to 77GHz which encompass from Medical Implant devices to car radars applications.
The programme will look send design and testing of various antenna types and their optimal matching with ASPAT diodes across a range of frequencies of interest to the industrial partner (linwave ltd). The main deliverable is the realisation of miniature, fully integrated RF circuits with very high sensitivity. The zero-bias feature of the diodes (and hence full integrated circuit) should also find applications in the Internet of Things (IoT) where ubiquitous sensors that do not require active power for operation should be very attractive.

PhD Programme: Literature review, state of the art in ASPAT devices, simulation using SILVACO, CST and ADS; measurements of fabricated diodes: data and parameters extraction, design and circuit layout of resonant circuits working at microwave and mm-wave frequencies.
