PhD Studentships – 3 studentships in developing and exploiting new “direct-write” methods for nanoscale construction using focused ion and electron beams.

In this project three students will develop and exploit new “direct-write” methods for nanoscale construction using focused ion and electron beams. The direct-write may be thought of like 3D printing, as opposed to industry-standard lithography which is like mass production with moulds. Direct write should be much better for quick, one-off research prototypes. Each student will become an expert in the both types of technique. Then each student will focus on a specific quantum technology platform: silicon single electron transistors incorporating implantation of single ions, superconducting devices, or photonic crystal cavities. These projects will be ideal for anyone wanting to gain entry into a rapidly expanding research field and the associated nascent industry, into which billions have already being pumped by governments keen to gain an edge.

You do not already need experience with focussed ion or electron beams or quantum technology devices. Training will also be carried out on the measurement tools and equipment. Once this training has been carried out you will then develop completely new fabrication processes specific to your own project. You will then optimize the properties of your devices, changing the process steps and structures to better understand the physics and move towards exiting new concepts and devices.

The supervisory team for the three students is Prof Ben Murdin (silicon impurity quantum optics), Dr Steve Clowes (semiconductor quantum transport), Dr David Cox (focussed ion beam technologies), Dr Marian Florescu (photonic crystals). We have a track record of publishing our results in very high impact journals such as Nature, Nature Photonics, Nature Communications, etc, and we anticipate the work that you do will generate this level of excitement.

We welcome applications from both women and men, from any background. We discriminate solely on the basis of potential, ability, skills and knowledge.

Fully funded PhD studentship in Terahertz light imaging (application closed)

Surrey University and the National Physical Laboratory have an EPSRC-funded Industrial CASE Studentship, available for start in Oct 2017.

We are developing techniques to position single donor atoms in silicon crystals with atomically precise location, and now we need to develop new techniques to image what we have made. The donor impurities are of major international interest for Quantum Technology, since each donor atom carries a single valence electron that can be imprinted with quantum information and used as a qubit. The challenge is that the atoms must be very cold and the signature transitions are far out in the infrared where imaging is not well developed. You will help to develop a new microscope and use it to image single donor atoms, within a £multi-million collaboration aiming to develop silicon quantum computer logic gates.

Normal EPSRC studentship eligibility requirements apply, i.e. you must be a UK citizen or UK resident to receive full funding. For further information, please contact Prof Ben Murdin: b.murdin (at) or Dr. Juerong Li: Closing date 1st June 2017.

Applications will be welcomed at any time. Offers can be made before the advertising deadline.
