Virtual Laboratory : Magneto-optics

We excite electron-hole pairs in either semiconductor heterostructures or nantube based samples and study the light which is emitted when they recombine (luminescence).

The emitted light gives information about the electronic state of the electron system. Try running a virtual experiment for yourself below.

We are currently studying the states of a two dimensional electron gas in high magnetic fields and low temperatures where the quantum Hall effect occurs. New particles and states of matter occur with excitations which have fractional charges and spin textures associated with the Fractional Quantum Hall Effect and the Quantum Hall Ferromagnet (Skyrmions).
