Circularly polarised electroluminescence from chiral excitons in vacuum-sublimed supramolecular semiconductor thin films
Rituparno Chowdhury, Marco D. Preuss, Hwan-Hee Cho +21
Materials with chiral electronic structures are of great interest. We report a triazatruxene, TAT, molecular semiconductor with chiral alkyl side chains that crystallises from solu…

Optical read and write of spin states in organic diradicals
Rituparno Chowdhury, Petri Murto, Naitik A. Panjwani +17
Optical control and read-out of the ground state spin structure has been demonstrated for defect states in crystalline semiconductors, including the diamond NV- center, and these a…

Extending the Defect Tolerance of Halide Perovskite Nanocrystals to Hot Carrier Cooling Dynamics
Junzhi Ye, Navendu Mondal, Ben P. Carwithen +16
Defect tolerance is a critical enabling factor for efficient lead-halide perovskite materials, but the current understanding is primarily on band-edge (cold) carriers, with signifi…
