Joining NEES Lab

This page is for students considering joining the lab. It describes what we work on, what you would learn here, and how admission and funding work. Please read it before writing to me.

What we work on

We study non-equilibrium electronic systems — the regime in which fluctuation, discreteness and dynamics, rather than averaged quantities, govern how a device behaves. Our central experimental tool is room-temperature single-electron measurement: by reducing a current until electrons pass one at a time, we can observe and control electron motion directly, and test non-equilibrium physics in a real device rather than only on paper. Current projects are described on the Research page.

What you will learn

Most groups working on non-equilibrium phenomena approach them from theory. Here you carry a problem through the entire chain yourself:

  • characterisation of silicon nanoscale transistors
  • precision electrical measurement, down to the femtoampere range
  • instrument control and automated measurement in Python
  • modelling and simulation in Python and Mathematica
  • data processing, statistical analysis and interpretation

Underpinning all of it is the physics you need in order to read your own results: semiconductor device engineering for understanding transistors, together with statistical mechanics and thermodynamics.

Admission and funding

Two things are worth knowing before you write to me.

  • Admission. Admission is decided by the Graduate School of Engineering Science through its own entrance examination, not by me individually. Whatever we agree between us, you will need to satisfy the graduate school's requirements. Entry terms, deadlines, required documents and language requirements are all set by the school and change from year to year, so please work from its current application guidelines.
  • Funding. You arrange your own funding — the MEXT scholarship, a scholarship from your home country, or private means. If you plan to study at your own expense, please make sure your funding covers the full length of the programme.
