Electrolyte-Gated Perovskite Transistors Functionalized with Conjugated Polymers

Interfacial Interaction Enables Enhanced Mobility in Hybrid Perovskite‐Conjugated Polymer Transistors with High‐k Fluorinated Polymer Dielectrics

“…This result indicates that the conjugated polymers has the ability to effectively reduce the surface traps of the perovskite by passivating A-site cation and X-site anion defects. [47][48][49][50] The BDT-based conjugated polymers exhibited more effective passivation of defects than P3HT polymer, however they still showed lower mobilities which were attributed to their lower molecular weights.…”

Organic–inorganic hybrid perovskite materials and their application in transistors

“…A remarkable mobility of 30.87 cm 2 V À1 s À1 was observed from a Py1/MAPbI 3 FET. 133 Noticeably, the working voltages of these as-described transistors were relatively low (|V th | o 2 V), which was the consequence of the high-k polymer or electrolyte gate dielectrics. These dielectric materials were also responsible for the improved charge densities in the channels and contributed to the high mobilities.…”

Multifunctional two-dimensional perovskite based solar cells for photodetectors and resistive switching

“…Recently, extensive research has been conducted to explore the application of halide perovskites (HPs) and organic materials in microelectronic devices beyond solar cells. [1][2][3][4] These devices include light-emitting diodes, 5 photodetectors (PDs), 6,7 thin film transistors, 8,9 resistive switching (RS) devices, 10,11 and artificial synapses. 12,13 There is growing interest in multifunctional devices that can replace multiple components with a single unit, offering space and weight savings for space-constrained applications while reducing energy consumption, aligning with the rising demand for miniaturized and intelligent devices.…”
