An alternative doping approach that exploits the use of organic donor/acceptor molecules for the effective tuning of the free electron concentration in quasi-2D ZnO transistor channel layers is reported. The method relies on the deposition of molecular dopants/formulations directly onto the ultrathin ZnO channels. Through careful choice of materials combinations, electron transfer from the dopant molecule to ZnO and vice versa is demonstrated.
报道了一种利用有机给体/受体分子来有效调节准二维 ZnO 晶体管通道层中自由电子浓度的替代掺杂方法。该方法依赖于将分子掺杂剂/制剂直接沉积在超薄 ZnO 通道上。通过仔细选择材料组合，证明了从掺杂分子到 ZnO 的电子转移和反之亦然。
