[Physics-talks] Special seminar in the Spring Break week (03/26, Wednesday)

[Arianna Mejia]

Hello,

Join us on March 26th to hear from Dr. Likun Wang in MSE at 3pm!

*Tunneling photocurrent spectroscopy of in-situ twisted 2D materials with
the optical quantum twisting microscope*

Dr. Likun Wang

Quantum Nano-Optoelectronics Group,
ICFO-The Institute of Photonic Sciences, Spain



*Abstract: *Quantum twisting microscope (QTM) is a new and powerful
platform to study in-situ twistronics and momentum-resolved band structure
imaging of 2D materials. Further combining it with light allows probing the
optical and optoelectronic properties of two layers of 2D materials stacked
on top of each other with a tunable twist angle. In this talk, I will
present the development of an optical quantum twisting microscope which is
equipped with both continuous wave lasers and home-built Fourier transform
infrared (FTIR) spectrometer based on a supercontinuum laser. Light induced
tunneling photocurrent spectroscopy is performed to study the photo
excitation process in different vertical tunnel junctions while tuning the
twist angle continuously.
