Though both the crystal structure and molecular orientation of organic semiconductors are known to impact charge transport in thin-film devices, separately accessing different polymorphs and varying the out-of-plane molecular orientation is challenging, typically requiring stringent control over film deposition conditions, film thickness, and substrate chemistry. Here we demonstrate independent...

Oriented film and pattern of TCNQ@Cu 3 (BTC) 2 (HKUST-1) fabricated via epitaxial growth exhibit anisotropic electrical properties toward MOF-based (flexible) thin-film smart device applications, such as transistors thermoelectric thin films.

A microfluidic device integrated with 3D thin film microelectrode arrays wrapped around serpentine-shaped microchannel walls has been designed, fabricated and tested for cell electrofusion. Each microelectrode array has 1015 discrete microelectrodes patterned on each side wall, and the adjacent microelectrodes are separated by coplanar dielectric channel wall. The device was tested to electrofu...

An unusual processing scheme has been developed for preparing single-phase cadmium stannate (Cd2SnO4 or CTO) films. Cd2SnO4 transparent conducting oxide (TCO) films have several significant advantages over conventional TCOs when applied to CdS/CdTe thin-film devices. They are more conductive, more transparent, have lower surface roughness, are patternable, and are exceptionally stable. Cd2SnO4-...

High performance thin-film transistors were fabricated using a new precursor of pentacene through a multiple spin-heat procedure. High quality pentacene thin films can be prepared by this method and hence a FET device can be made in a top-contact configuration. The device exhibited a remarkable field-effect mobility of 0.38 cm(2) V(-1) s(-1) with an on/off ratio of 10(6).

This paper reports on the measurement of elastic modulus of thin film materials by a magnetostrictive sensor. Thin film materials of Cu, Cr, Al, Au, Sn, In, Au-rich lead free solder (AuSn) and SiC were sputter deposited onto well defined strips of Metglas sensor. The elastic modulus of the thin film materials was determined by measuring the resonant frequency of the sensors before and after fil...

A thin film Co nanomagnet in the shape of an elongated hexagon has been incorporated in a vertical device structure consisting of the nanomagnet and a thin Cu spacer layer formed on top of a thick Co film. The spin-polarized current flowing between the nanomagnet and the Co film is used to abruptly switch the magnetic alignment of the nanomagnet relative to that of the thick Co layer by the tra...

We report the implementation of three dimensionally cross-linked, organic nanodielectric multilayers as ultrathin gate dielectrics for a type of thin film transistor device that uses networks of single-walled carbon nanotubes as effective semiconductor thin films. Unipolar n- and p-channel devices are demonstrated by use of polymer coatings to control the behavior of the networks. Monolithicall...

A single walled carbon nanotube (SWCNT)-based three-electrode system was fully integrated on glass substrates using a standard microfabrication process and electrochemically characterized using cyclic voltammetry. O(2) plasma functionalization of the SWCNT film working electrode for achieving high sensitivity was voltammetrically optimized with respect to the plasma power and treatment time. Ch...
