ABSTRACTA new method of fabricating short channel α-Si TFTs has been developed. One-micrometer channel length α-Si thin-film field effect transistors have been fabricated and tested. Threshold voltages as low as 1.9V and field-effect mobilities as high as 1 cm 2/V-sec are reported. These devices were fabricated by techniques compatible with the production of large area liquid crystal displays.

Organic thin-film field-effect transistors (OTFTs) are emerging as attractive candidates for low-price, large-area, and flexible circuit applications. A variety of organic compounds have been utilized as active semiconductor materials for OTFTs, among which phthalocyanine compounds have attracted considerable attention owing to their remarkable chemical and thermal stability as well as good field-effect performance. Here, we review recent results on the phthalocyanine-based OTFTs. The correlation between the crystal packing structure and the charge transport property is discussed, and we conclude with a description of the future prospects for phthalocyanine-based OTFTs.

ABSTRACTApplication of tensile strain to the Si(100) lattice is known to enhance carrier mobility in field effect transistors through modification of the Si band structure. Si is conventionally placed under tensile strain using methods such as Si3N4 capping for strained channel devices, and epitaxial growth of Si on a strain graded SiGe substrate for large area strain. The latter case preserves and propagates threading dislocations, and both cases require use of a bulk rigid substrate, which prohibits the use of strained Si in applications such as flexible electronics, or indeed in any application where strained Si is desirable on a non-epitaxial substrate. Elastically strained, single-crystal, Si-based nanomembranes, in which the release of a Si/SiGe/Si heterostructure from its growth substrate allows elastic strain sharing between the layers, circumvent these issues. These nanomembranes are extremely flexible, virtually dislocation-free, and transferable to almost any other surface.

In recent years, tetrathiafulvalene (TTF) and its derivatives have been used as semiconducting materials for organic field-effect transistors (OFETs). In this review, we summarize the recent progress in the field of TTF-based OFETs. We introduce the structure and operation of OFETs, and focus on TTF derivatives used in OFETs. TTF derivatives used in OFETs can be divided into three parts by the semiconductor's morphology and the device fabrication technique: (1) TTF derivatives used for single-crystal OFETs, (2) TTF derivatives used for vacuum-deposited thin-film OFETs, and (3) TTF derivatives used for solution-processed thin-film OFETs. The single-crystal OFETs based on TTF derivatives were fabricated by drop-casting method and showed high performance, with the mobility up to 1.4 cm2/Vs. The vacuum-deposited thin-film OFETs based on TTF derivatives were well developed, some of which have shown high performance comparable to that of amorphous silicon, with good air-stability. Although the mobilities of most solution-processed OFETs based on TTF derivatives are limited at 10-2 cm2/Vs, the study on solution-processable TTF derivatives and their devices are promising, because of their low-cost, large-area-coverage virtues. The use of organic charge-transfer (OCT) compounds containing TTF or its derivatives in OFETs is also included in this review.

Semiconducting polythiophene polymers are promising materials for the generation of large-area and flexible electronics. However, field effect transistors (FETs) using semiconducting polymers as the channel material possess relatively poor mobility,...
