Strain fingerprinting of exciton valley character
Abhijeet Kumar, Denis Yagodkin, Roberto Rosati +13
Momentum-indirect excitons composed of electrons and holes in different valleys define optoelectronic properties of many semiconductors, but are challenging to detect due to their…
Probing the formation of dark interlayer excitons via ultrafast photocurrent
Denis Yagodkin, Elias Ankerhold, Abhijeet Kumar +5
Optically dark excitons determine a wide range of properties of photoexcited semiconductors yet are hard to access via conventional spectroscopies. Here, we develop a time-resolved…
Nanomechanical absorption spectroscopy of 2D materials with femtowatt sensitivity
Jan N. Kirchhof, Yuefeng Yu, Denis Yagodkin +9
Nanomechanical spectroscopy (NMS) is a recently developed approach to determine optical absorption spectra of nanoscale materials via mechanical measurements. It is based on measur…
