Link between hopping models and percolation scaling laws for charge transport in mixtures of small molecules
Kim, Jang-Joo; Ha, Dong-Gwang; Baldo, Marc A (American Institute of Physics (AIP), 2016-04)Mixed host compositions that combine charge transport materials with luminescent dyes offer superior control over exciton formation and charge transport in organic light emitting devices (OLEDs). Two approaches are ... -
Turbocharged molecular discovery of OLED emitters: from high-throughput quantum simulation to highly efficient TADF devices
Gómez-Bombarelli, Rafael; Aguilera-Iparraguirre, Jorge; Hirzel, Timothy D.; Aspuru-Guzik, Alán; Ha, Dong-Gwang; e.a. (SPIE, 2016-09)Discovering new OLED emitters requires many experiments to synthesize candidates and test performance in devices. Large scale computer simulation can greatly speed this search process but the problem remains challenging ...
