ioARPES
operando Angle Resolved Photoemission /U125-2
ioARPES will be built upon the strengths of BESSY II in angle resolved photoemission for electronic band structure determination, and will provide highest energy and angle (momentum) resolution and improved spatial resolution. In a future transition from transistor-based electronics to versatile quantum-material-based technologies, understanding electronic band structures and their tunability by external stimuli such as electric current, bias voltage, electric fields, temperature or strain is crucial. While ioARPES will not strive for record spatial resolution it puts its strength on operando experiments.
Uniqueness: The versatile application of electric fields, bias voltages, mechanical strain at low temperatures in the laboratory-on-a-chip is the main purpose of the instrument.
