Spin Arpes Lab Ntnu

Spin Arpes Lab Ntnu We use a method called spin and angle resolved photoelectron spectroscopy (spin arpes) to investigate magnetic and topological materials. spin arpes is based on the photoelectric effect, i.e. the excitation of photoelectrons at a material surface upon irradiation with monochromatic light. We answer these questions by developing a high resolution spin resolved arpes setup that has the ability to visualize spin texture in electronic band structures.

Spin Arpes Lab Ntnu Laboratories laboratories quspin has four laboratories within our experimental research activities: spin arpes lab molecular beam epitaxy of antiferromagnets (mbe) lab quantum magnonics lab functional topological systems lab. Using the combination of our existing knowledge and background, together with the utilization of the latest developments internationally, we have been able to design and build a state of the art spin arpes instrument.

We employ angle resolved photoelectron spectroscopy (arpes) using advanced instrumentation in the arpes lab at ntnu and at international synchrotron radiation facilities, such as petra iii at desy (hamburg, germany).

Spin arpes allow us to directly address these points experimentally. our experiments are performed in the laboratory at ntnu and at international synchrotron radiation facilities, such as petra iii at desy (hamburg). Arpes is the technique for revealing the valance band structure and fermi level which is fundamental for understanding electron transport, band gap phenomena and spin related effects. This technique allows researchers to observe the spin helical structure caused by band inversion which splits spin up and spin down states into individual bands. Surface induced symmetry breaking enhances spin orbit interaction and induces spin polarized electrons on the surface of ptco2. measured spin polarization provides evidence of the presence of weyl electrons in mote2. spin resolved arpes data confirm the helical spin texture of the two surface states in pdte2 and therefore their topological nature.
