Polariton hyperspectral imaging of two-dimensional semiconductor crystals
Christian Gebhardt, Michael Förg, Hisato Yamaguchi +8
Atomically thin crystals of transition metal dichalcogenides (TMDs) host excitons with strong binding energies and sizable light-matter interactions. Coupled to optical cavities, m…
Free-standing bialkali photocathodes using atomically thin substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
We report successful deposition of high quantum efficiency (QE) bialkali antimonide K2CsSb photocathodes on graphene films. The results pave a pathway towards an ultimate goal of e…
The role of lattice mismatch on the emergence of surface states in 2D hybrid perovskite quantum wells
M. Kepenekian, B. Traore, J. -C. Blancon +9
Surface states are ubiquitous to semiconductors and significantly impact the physical properties and consequently the performance of optoelectronic devices. Moreover, surface effec…
