“…Transistor‐type nonvolatile memories have received extensive attention on account of their nondestructive read‐out, single transistor architecture and compatibility with complementary integrated circuits . One common class is floating‐gate flash memory which consists of gate electrode, blocking dielectric (prevent charge transport between gate electrode and floating gate), floating gate (store charges), tunneling layer (determine program/erase speed and prevent leakage of trapped carriers), semiconducting active layer and source/drain electrodes.…”

Ambipolar transistors represent a class of transistors where positive (holes) and negative (electrons) charge carriers both can transport concurrently within the semiconducting channel. The basic switching states of ambipolar transistors are comprised of common off-state and separated on-state mainly impelled by holes or electrons. During the past years, diverse materials are synthesized and utilized for implementing ambipolar charge transport and their further emerging applications comprising ambipolar memory, synaptic, logic, and light-emitting transistors on account of their special bidirectional carrier-transporting characteristic. Within this review, recent developments of ambipolar transistor field involving fundamental principles, interface modifications, selected semiconducting material systems, device structures, ambipolar characteristics, and promising applications are highlighted. The existed challenges and prospective for researching ambipolar transistors in electronics and optoelectronics are also discussed. It is expected that the review and outlook are well timed and instrumental for the rapid progress of academic sector of ambipolar transistors in lighting, display, memory, as well as neuromorphic computing for artificial intelligence.

“…One of the widely used strategies is to integrate multicomponents inside active materials so as to combine varied electronic and optoelectronic functions to work synergistically. As a result, a variety of organic devices based on these multicomponent active materials have been developed, including ambipolar organic field‐effect transistors (OFETs), organic light‐emitting diodes (OLEDs) and organic light‐emitting transistors (OLETs), organic photovoltaics (OPVs), memory devices, and complementary circuits . However, integrating multicomponents together often ends up with relatively disordered molecular packing in amorphous or polycrystalline states, leading to moderate performance.…”

Organic single-crystalline heterojunctions are composed of different single crystals interfaced together. The intrinsic highly ordered heterostructure in these multicomponent solids holds the capacity for multifunctions, as well as superior charge-transporting properties, promising high-performance electronic applications such as ambipolar transistors and solar cells. However, this kind of heterojunction is not easily available and the preparation methods need to be developed. Recent advances in the efficient strategies that have emerged in yielding high-quality single-crystalline heterojunctions are highlighted here. The advantages and limitations of each strategy are also discussed. The obtained single-crystalline heterojunctions have started to exhibit rich physical properties, including metallic conduction, photovoltaic effects, and so on. Further structural optimization of the heterojunctions to accommodate the electronic device configuration is necessary to significantly advance this research direction.

“…To date, versatile solution‐processable photoactive materials showing intense light absorption in the wavelengths ranging from ultraviolet to the near‐infrared region have been exploited in electronic devices to enable a photon‐recording functionality . Among which, the transistor‐type memory using a floating‐gate architecture has been considered as a promising platform to realize long retention times over several years, because the spatially‐confined metallic or semiconducting floating‐gate elements act as a charge‐trapping site to electrically isolate the trapped charges from the surrounding insulator effectively . Based on similar principle, it is feasible to create charge trapping/storing by using photons instead of an electrical field.…”

Nonvolatile Perovskite‐Based Photomemory with a Multilevel Memory Behavior

Solution-processable organic-inorganic hybrid perovskite materials with a wealth of exotic semiconducting properties have appeared as the promising front-runners for next-generation electronic devices. Further, regarding its well photoresponsibility, various perovskite-based photosensing devices are prosperously developed in recent years. However, most exploited devices to date only transiently transduce the optical signals into electrical circuits while under illumination, which necessitates using additional converters to further store the output signals for recording the occurrence of light stimulation. Herein, a nonvolatile perovskite-based floating-gate photomemory with a multilevel memory behavior is demonstrated, for which a floating gate comprising a polymer matrix impregnated with perovskite nanoparticles is employed. Owing to the well photoresponsibility introduced by the embedded nanoparticles, the device is enabled to access multiple wavelength response and the functionalities of recording power/time-dependent illumination under no vertical electrical field. Intriguingly, a nonvolatility of photorecording exceeding three months with a high On/Off current ratio over 10 can be achieved.
