“…The most thoroughly studied OPBT relying on hot carrier transmission is a p-type OPBT proposed by Chan and Chu [19,20,[22][23][24][25][26]. The structure consists of a gold bottom electrode (collector), CuPc, Pentacene, a thin layer of LiF, a thin aluminum layer as base electrode, NPB, Pentacene, and gold as emitter electrode.…”

Organic switching devices such as field effect transistors (OFETs) are a key element of future flexible electronic devices. So far, however, a commercial breakthrough has not been achieved because these devices usually lack in switching speed (e.g. for logic applications) and current density (e.g. for display pixel driving). The limited performance is caused by a combination of comparatively low charge carrier mobilities and the large channel length caused by the need for low-cost structuring. Vertical Organic Transistors are a novel technology that has the potential to overcome these limitations of OFETs. Vertical Organic Transistors allow to scale the channel length of organic transistors into the 100 nm regime without cost intensive structuring techniques. Several different approaches have been proposed in literature, which show high output currents, low operation voltages, and comparatively high speed even without sub-μm structuring technologies. In this review, these different approaches are compared and recent progress is highlighted.

“…Vertical organic transistors have attracted lots of attentions recently because of their excellent device performances, such as high on/off current ratio, , low operation voltage, , and high output current density. , Contrary to the organic field-effect transistors in which the source and drain electrodes are in the same plane, the channel length in vertical organic transistors is determined by the thickness of the organic layer which vertically separates the electrodes for carrier injection and collection. The short vertical channel length can be easily achieved by reducing the organic layer thickness between electrodes.…”

We demonstrated a large-area nanopatterning technique with the help of a non-close-packed PS sphere layer over a large-area substrate. The non-close-packed PS sphere layer is fabricated by blade coating method. It was demonstrated that non-close-packed PS spheres can be achieved within an area of 18 cm × 25 cm on a rigid glass substrate and within an area of 10 cm × 10 cm on a flexible substrate. We also demonstrated that the blade-coated non-close-packed PS sphere layer was suitable for the mass production of vertical organic transistors over a large area.

“…4,5 Thus this technology will support a complementary logic. 15 carriers through the base are discussed, which were already mentioned for inorganic permeable base transistors (PBT). 16,17 If the base contact is very thin (10-15 nm), but closed, a hot carrier mechanism has been suggested.…”

Due to their effective short channel length of only a few hundred nanometers, vertical organic triodes (VOTs) have a high potential to overcome problems of low current densities and switching speed in current organic field effect transistors (OFETs). Furthermore, VOTs are easy to build because no sub-structuring of the base contact is necessary. Nevertheless, these devices are poorly investigated. In literature, two different working mechanisms are suggested: hot carrier transport through the metallic base or transport of charge carriers through a permeable base electrode. As a strong asymmetry is expected for function principle based on hot carriers, we are able to distinguish between both mechanisms by examining the bidirectional transmission properties of the VOT consisting of electron transporting materials. We show that high transmission values (>95%) are possible for both directions, suggesting a base contact with openings forming a grid electrode.
