Department of Physics

Physics is the foundation for natural sciences, and also has practical implications for our everyday lives. In fact, modern life is dominated by technological developments based on discoveries in physics, from ultra-fast computers to renewable energy technologies.

Our research spans a broad spectrum of natural sciences and technology, which in turn allows us to offer an education that provides a solid basis for future careers. Physics research is carried out in experimental as well as theoretical fields, often across conventional boundaries between disciplines. Our central research areas are materials science, nanoscience, surface physics, modern optics, astrophysics, solar energy, biophysics, and medical technology. Research staff at the institute make a special effort to increase the awareness and understanding of the importance and impact of physics in our society.

Department of Physics currently employs about 180 people. On average, about 2000 NTNU students a year take Physics courses.

Abstract

By suppressing an undesirable surface Umklapp process, it is possible to resolve the two most occupied states (1Γ and 2Γ) in a buried two-dimensional electron gas (2DEG) in silicon. The 2DEG exists because of an atomically sharp profile of phosphorus dopants which have been formed beneath the Si(001) surface (a δ-layer). The energy separation, or valley splitting, of the two most occupied bands has critical implications for the properties of δ-layer derived devices, yet until now, has not been directly measurable. Density functional theory (DFT) allows the 2DEG band structure to be calculated, but without experimental verification the size of the valley splitting has been unclear. Using a combination of direct spectroscopic measurements and DFT we show that the measured band structure is in good qualitative agreement with calculations and reveal a valley splitting of 132 ± 5 meV. We also report the effective mass and occupation of the 2DEG states and compare the dispersions and Fermi surface with DFT.

Norwegian Centre of Transmission Electron Microscopy (NORTEM) is a large scale infrastructure project with three partners: NTNU, SINTEF and UiO. We followed the realization of the state-of-the-art facility from delivery and installation to use of the microscopes by researchers and students. Here is a series of photos documenting the delivery, installation and use of the new microscopes.

NorTEMnet workshop on STEM in Trondheim

The 4th NorTEMnet workshop on advanced TEM is organized at NTNU in Trondheim, January 8-10. 2014. This workshop will be focused on STEM - there will be three days of lectures, computer exercises and hands-on practical sessions using the new NORTEM infrastructure in Trondheim (JEOL 2100, 2100F and ARM200F).
