A thin film transistor is disclosed comprising comprises a substrate, a dielectric layer, and a semiconductor layer. The semiconductor layer, which is crystalline zinc oxide preferentially oriented with the c-axis perpendicular to the plane of the dielectric layer or substrate, is prepared by liquid depositing a zinc oxide nanodisk composition. The thin film transistor has good mobility and on/off ratio.

摘要:
Disclosed is an item, for example a document, including a substrate having thereon a multiplicity of separate printed markings, wherein the printed markings include both conductive printed markings and substantially non-conductive printed markings. The different conductive and substantially non-conductive regions on the substrate can be detected, for example by measuring the resistance or current of each printed marking. The pattern of different conductive and substantially non-conductive regions can be used as a security pattern of authenticity that cannot be replicated by standard office equipment, and/or can be used to encrypt information in binary code form in the item. A system for forming and detecting the different printed markings is also described.
摘要:
A thin-film transistor (TFT) with dual-layer source and drain electrodes is provided. Each source and drain electrode comprises a first layer and a second layer. The first layer has a work function which differs from the energy level of the semiconductor by at least 0.5 eV and the second layer has a work function matching the energy level of the semiconductor. The semiconductor has a short channel length.
