The Department of Physics and Astronomy hereby invites everyone interested to a docentship lecture in the subject of Physics.
Chairperson: Professor Björgvin Hjörvarsson
Representative of the Docentship Committee: Professor Carlos Pérez de los Heros
Abstract:
The physical properties of many material systems are governed by their characteristics at interfaces, often hidden beneath the surface. In this lecture, I will demonstrate how such structures can be revealed using neutron reflectometry. Through its wave-particle duality, the neutron scatters and interferes with itself within these structures, creating the illusion of a reflected beam. I will provide an overview of the technique, explain the origin of this illusion, and present examples from modern scientific research, highlighting how the technique can be applied to study the properties of energy storage materials.
The lecture is an obligatory teaching test for those applying for admittance as docent and it should be possible for students and others with basic academic education in the relevant field to follow it. The lecture lasts 40-45 minutes with subsequent discussion. The lecture will be given in English.
