Hot-Carriers’ Effect on the Performance of Organic Schottky Diodes

IEEE Access, 2020
Because thermionic emission or tunneling occurs when carriers overcome or tunneling through the barrier for any Schottky diode, hot carriers caused by the applied electric field can enhance carrier thermionic emission or carrier tunneling.

Dirac Surface‐State Driven Broad Spectral Band Low Quantum Energy Photoresponse in Quaternary Topological BiSbSe2Te

Advanced Science, EarlyView.
Quaternary topological BiSbSe2Te are synthesized and demonstrates a broad spectral band photoresponse, ranging from infrared to terahertz and to millimeter waves, with a particular excellence on detection of low quantum energy terahertz photons. The observed photoresponse is attributed to the excitation of plasmonic nonequilibrium electrons originating
