Ultrathin Air-Stable n-Type Organic Phototransistor Array for Conformal Optoelectronics

Air-stable, high-performance organic n-channel transistors

Organic thin-film transistors (TFTs) are of interest for flexible, large-area electronics applications, such as rollable or foldable information displays, conformable sensor arrays, and plastic circuits [1]. The vast majority of the organic TFTs that have been developed to date are p-channel TFTs, meaning that the electric currents in these transistors are due to the flow of positive charge car...

Ultrathin metal-organic framework array for efficient electrocatalytic water splitting

Two-dimensional metal-organic frameworks represent a family of materials with attractive chemical and structural properties, which are usually prepared in the form of bulk powders. Here we show a generic approach to fabricate ultrathin nanosheet array of metal-organic frameworks on different substrates through a dissolution-crystallization mechanism. These materials exhibit intriguing propertie...

Ultra-low voltage air-stable polyelectrolyte gated n-type organic thin film transistors

An air-stable low-bandgap n-type organic polymer semiconductor exhibiting selective solubility in perfluorinated solvents.

A thin-film transistor: An n-type polymer semiconductor, poly(2,3-bis(perfluorohexyl)thieno[3,4-b]pyrazine), was synthesized through a Pd-catalyzed polycondensation employing a perfluorinated multiphase solvent system. This is the first example of an n-type polymer semiconductor with exclusive solubility in fluorinated solvents. The fabrication of organic field effect transistors containing thi...

Conjugate acene fused buckybowls: evaluating their suitability for p-type, ambipolar and n-type air stable organic semiconductors.

Elaborate and exhaustive first principles calculations were carried out to screen the novel properties of a series of acene fused buckybowls. The acene fused compounds exhibit hole transport property due to their higher electron injection and lower hole transport barrier relative to the work function potential of Au electrodes. The higher HOMO and lower LUMO energy levels suggest lower hole and...
