Main Applications of ARPES today?

[Mr.Brown]

Hi,
I´m preparing a paper on ARPES and wanted ask what the main applications of ARPES are nowadays?

I allready understand that high temperature superconductors are one main region of interest but what else ?

Thanks

ARPES technique is used to obtain the band structure of a material. This is crucial because the band structure practically reveals almost ALL of the properties of the material that are within the first few eV.

You should consult various photoemission texts as references, such as Hufner's "Photoelectron Spectroscopy" (springer).

for your question! ARPES, or angle-resolved photoemission spectroscopy, has become an important tool in the study of electronic properties in various materials. Some of the main applications of ARPES today include:

1. Investigating the electronic structure of materials: ARPES is commonly used to study the electronic structure of materials, including metals, semiconductors, and insulators. It provides information on the energy and momentum of electrons, which is crucial in understanding the electronic properties of a material.

2. Characterizing novel materials: ARPES has been instrumental in characterizing new and emerging materials, such as topological insulators, graphene, and other 2D materials. These materials have unique electronic properties that can be studied using ARPES.

3. Probing surface and interface states: ARPES is a powerful technique for studying surface and interface states in materials. By measuring the electronic structure at different angles and energies, researchers can gain insight into the surface and interface properties of a material.

4. Studying correlated electron systems: ARPES has been used to study strongly correlated electron systems, such as high-temperature superconductors, where traditional methods of studying electronic structure may not be as effective. ARPES can provide valuable information on the electronic interactions and correlations in these systems.

5. Understanding quantum materials: ARPES is also being used to study quantum materials, which exhibit exotic electronic properties due to their quantum nature. This includes materials with topological order, unconventional superconductors, and materials with strong spin-orbit coupling.

In addition to these main areas of application, ARPES is also used in fields such as nanotechnology, surface science, and materials science. As technology continues to advance, ARPES is expected to play a crucial role in the discovery and understanding of new materials and their electronic properties.
