Manipulating Electrons in Single Atomic Layers Graphene Transistors and in Fruit Flies

19:00 – 21:00 9 May 2013

Glyndwr Lecture Theatre D, Swansea University.

Speakers: Laurence Eaves (Research Professor, School of Physics and Astronomy in the University of Nottingham)

Electrons not only hold together the solid and liquid matter in the world around us, but almost all of our modern technology relies on the properties of electrons.  In this talk, Prof Eaves will describe two novel ways of manipulating electrons: the first part of the talk will discuss the remarkable electronic properties of electrons in graphene, which is a new wonder material consisting of a single atomic layer of carbon atoms bound together in a planar hexagonal array.  Prof Eaves will describe some recent work done with colleagues at the University of Manchester to make a new type of field-effect transistor in which electrons undergo quantum tunnelling from one graphene layer to another.  In the second part of the talk, the physics of diamagnetic levitation will be outlined, in which the orbits of electrons in atoms are modified thereby creating a force which can balance gravity.  Diamagnetic levitation can be used to investigate a variety of physical and biological phenomena, including the properties of raindrops to the behaviour of fruit flies in enhanced and zero gravity conditions.

Light refreshments after lecture.
