|The name "charge injection" describes the operation of a generic class of electronic and optoelectronic multiterminal semiconductor devices, based on the real space transfer of hot carriers over a potential barrier into adjacent and separately contacted layers. Charge injection devices enable the implementation of compact optoelectronic gates endowed with a powerful logic functionality. Keywor...

Here we propose and analyze the behavior of a FET–like switching device, the Mott transition field effect transistor, operating on a novel principle, the Mott metal–insulator transition. The device has FET-like characteristics with a low “ON” impedance and high “OFF” impedance. Function of the device is feasible down to nanoscale dimensions. Implementation with a class of organic charge transfe...

As electrons are transferred through a radiation damaged Charge Coupled Device (CCD), they may encounter traps in the silicon in which they will be captured and subsequently released. This capture and release of electrons can lead to a ‘smearing’ of the image. The dynamics of the trapping process can be described through the use of Shockley-Read-Hall theory, in which exponential time constants ...

The transfer of chemical vapour deposited graphene from its parent growth catalyst has become a bottleneck for many of its emerging applications. The sacrificial polymer layers that are typically deposited onto graphene for mechanical support during transfer are challenging to remove completely and hence leave graphene and subsequent device interfaces contaminated. Here, we report on the use of...

Introduction Rechargeable batteries are present in a variety of devices. The act of recharging them generally involves a charger wired to a wall outlet being plugged into the device. The charger can determine the type of charge the batteries receive and therefore determine the cycle life of the batteries. Wireless power transfer is on the cutting edge of the battery charging world. There are el...

This review summarizes the most widely used mechanisms in memory devices based on conjugated polymers, such as charge transfer, space charge traps, and filament conduction. In addition, recent studies of conjugated polymers for memory device applications are also reviewed, discussed, and differentiated based on the mechanisms and structural design. Moreover, the electrical conditions of conjuga...

Blending organic electron donors and acceptors yields intermolecular charge-transfer states with additional optical transitions below their optical gaps. In organic photovoltaic devices, such states play a crucial role and limit the operating voltage. Due to its extremely weak nature, direct intermolecular charge-transfer absorption often remains undetected and unused for photocurrent generatio...
