Projects Available

*/**Unconventional Computing using a Materials Science Approach
H. Bhaskaran

We want to achieve something unusual - creating a computing system where data storage and processing are closely linked using a materials science approach. In this exciting and pioneering project we aim to create nanoscale devices using phase change materials, and investigate arithmetic computations on these devices - this is our attempt to mimic biological computing processes (albeit at a very early stage). See recent publications on our Advanced nanoscale Engineering Group website: http://nanoeng.materials.ox.ac.uk

This is difficult to achieve, and so we need very, very bright and motivated colleagues. This project provides significant scope for a doctoral student potentially to effect a large-scale impact in the future of computing. We also have several international academic collaborations for this project, and hence there may be a possibility of opportunities for the student to travel to partner institutions in Germany and the USA

This project has the potential to enable the DPhil student to become an expert in phase change materials and memories as well as advanced measurement techniques. All our projects allow for significant creative contributions and the right DPhil candidate will have the freedom to shape research directions.

Your profile will be one of a highly motivated and very able student; the former evidenced perhaps by previous stints in research laboratories. The successful candidate (i) is most likely to have achieved or be predicted to achieve at least a first class honours degree, or equivalent, at undergraduate level in Physics, Materials, Engineering or a closely related field, (ii) may have a Masters level qualification in one of these subject areas too (a UK Integrated UG Masters qualification meets this level of qualification) and (iii) will possess a deep desire to carry out independent experimental research. You must like working on hands-on laboratory experiments and have the desire to try out and refine many novel ideas. Evidence of your initiative and ability to work collaboratively is desirable, including in the context of an experimental project.

Candidates are considered in the January 2018 admissions cycle which has an application deadline of 19 January 2018.

This 3.5-year EPSRC DTP studentship will provide full fees and maintenance for a student who has home fee status (this includes an EU student who has spent the previous three years (or more) in the UK undertaking undergraduate study). The stipend will be at least £15,553 per year. Other EU students should read the guidance at http://www.materials.ox.ac.uk/admissions/postgraduate/eu.html for further information about eligibility.

Any questions concerning the project can be addressed to Professor Harish Bhaskaran (harish.bhaskaran@materials.ox.ac.uk). General enquiries on how to apply can be made by e mail to graduate.studies@materials.ox.ac.uk. You must complete the standard Oxford University Application for Graduate Studies. Further information and an electronic copy of the application form can be found at http://www.ox.ac.uk/admissions/postgraduate_courses/apply/index.html.

Nanorobots for pick and place assembly of nano particles
H. Bhaskaran

We have an ambitious plan to deliver pick-and-place manufacturing at the nanoscale. To realize our ambitions, we are looking for a team member to pursue the doctorate on fundamental aspects of nanoscience, including the study of surface forces at the nanoscale and the ability to attract single nanoparticles reliably, and place them in a manner similar to automobile assembly - except this is at the nanoscale. This project is in close collaboration with Asylum Research of Santa Barbara USA, IBM Research - Zurich, Switzerland and the Microelectronics iNets with potential opportunities to travel to partner sites. 

The DPhil student working on this project will become an expert in advanced nanomanufacturing techniques, atomic force microscopy and nanoparticle assembly. All our projects allow for significant creative contributions and the right DPhil candidate will have the freedom to shape research directions.

Your Profile:
Your profile will be one of a highly motivated undergraduate (evidenced by previous stints in Research laboratories), first class honors degree (or equivalent) earning undergraduate in Physics, Materials, Engineering or a closely related field with a deep desire to carry out independent experimental research. You must like working on hands-on laboratory experiments and have the desire to try out many novel ideas. Evidence (via references) of initiative and ability to work collaboratively would be a plus, as this is an experimental project involving many collaborations.

Advanced nano materials characterization via atomic force microscopy
H. Bhaskaran

Nanoparticle toxicity is of high interest because of emerging concerns regarding their environmental impact. However, recent methods to manufacture nanoparticles using bio-inspired processing have been reasonably successful. The big question is: what is the difference between such bio-inspired processing routes and conventional routes. The DPhil student who will work on this project will pursue very advanced atomic force microscopy techniques in our laboratory to understand how surface texture at the nanoscale, as well charge contribute to theor toxicity. 

Our group is very well set-up to perform these measurements. We are now in possession of one of the most advanced atomic force microscopes with excellent collaborations with Asylum Research in Santa Barbara. Thus a DPhil student will be able to start on this project with plenty of informal as well as formal mentoring and support.

Nanomechanical Systems (NEMS) based on 2D materials
H. Bhaskaran

Nanoelectromechanical systems (NEMS) are systems where a tiny mechanical element is fabricated to add certain functionality to a device or a system. These systems are functional not only because they occupy less space, but more so because they can perform functions that larger devices cannot or carry out certain tasks with greater precision and efficiency. Our group is seeking DPhil students to carry on this work starting from October 2014. The focus will be on using non-traditional materials, especially 2D materials, in NEMS devices. We will also seek to study fundamental aspects of materials science, which will help us create even better devices in future.

An incoming DPhil student will have significant advantages: our experimental capability in this area is now set-up, and we have some of the most advanced instrumentation in the field. Our group has several individuals who can informally work with the student, so the student will not feel lost in their first few months.
