Solution-Processed Organic-Inorganic Perovskite Field-Effect Transistors with High Hole Mobilities.
A very high hole mobility of 15 cm2V-1s-1along with negligible hysteresis are demonstrated in transistors with an organic-inorganic perovskite semiconductor. This high mobility results from the well-developed perovskite crystallites, improved conversion to perovskite, reduced hole trap density, and improved hole injection by employing a top-contact/top-gate structure with surface treatment and MoOxhole-injection layers.
