- Abstract
We report the development of low operating voltages in inorganic-organic hybrid light-emitting transistors (HLETs) based on a solution-processed ZrO
x gate dielectric and a hybrid multilayer channel consisting of the heterojunction In2 O3 /ZnO and the organic polymer "Super Yellow" acting as n- and p-channel/emissive layers, respectively. Resulting HLETs operate at the lowest voltages reported to-date (<10 V) and combine high electron mobility (22 cm2 /(V s)) with appreciable current on/off ratios (≈103 ) and an external quantum efficiency of 2 × 10-2 % at 700 cd/m2 . The charge injection, transport, and recombination mechanisms within this HLET architecture are discussed, and prospects for further performance enhancement are considered.- Published
