Perovskite Light-Emitting Devices with Doped Hole Transporting Layer [PDF]
Molecules, 2021 Perovskite quantum dots (PQDs) have drawn global attention in recent years and have been used in a range of semiconductor devices, especially for light-emitting diodes (LEDs). However, because of the nature of low-conductive ligands of PQDs and surface and bulk defects in the devices, charge injection and transport should be carefully managed in order ...

Semiconductivity Transition in Silicon Nanowires by Hole Transport Layer [PDF]
Nano Letters, 2020 The surface of nanowires is a source of interest mainly for electrical prospects. Thus, different surface chemical treatments were carried out to develop recipes to control the surface effect. In this work, we succeed in shifting and tuning the semiconductivity of a Si nanowire-based device from n- to p-type.
