Job Opportunities


Research Associate - Semiconductor Physics (Fixed Term)

Fixed-term: The funds for this post are available for 12 months in the first instance.

The Semiconductor Physics Group of the Department of Physics, University of Cambridge, invites applications for a Postdoctoral Research Associate to work on developing a versatile quantum multiplexing instrument for quantum technology research.

The role is funded by the EPSRC research grant and will be managed by Professor Charles G. Smith. The Semiconductor Physics Group is engaged in research into advanced semiconductor devices and has a number of clean rooms, housing extensive semiconductor processing facilities, including optical lithography, metals deposition, dry and wet etching, dicing, bonding, ellipsometry and scanning probe microscopy etc. It also has an Ultra High Resolution E-beam Lithography suite which provides services for both internal and external customers.

Applications are invited for a Research Associate post to perform research on scaling up of arrays of coupled quantum devices at cryogenic temperatures. The candidate (who should have a PhD) will help put together a dilution refrigerator that can be used for radio frequency read out of multiple quantum devices working at temperatures below 100mK and in a large B field. This project builds on our early research where we have been able to measure and characterize 256 quantum devices on a single GaAs heterostructure chip at cryogenic temperatures. The successful candidate will help set up a cryogen-free dilution refrigerator facility that will allow the fast radio frequency readout of the quantum properties of many coupled quantum devices including arrays of quantum dots for quantum technology applications. The candidate will need to work with a number of users to demonstrate the system operation and they also will be required to develop their own experiments on the system.

The successful candidate will need to pursue scientific investigation from the conception stage through to publication and have a strong background in radio frequency measurements at cryogenic temperatures.

Applicants must possess knowledge or experience of semiconductor processing techniques an measuring nano-devices at cryogenic temperatures.
