ZnO-Based Inverters for Flexible Electronics

Gutierrez-Heredia G., Mejia I., Rivas-Aguilar M.E., Aguirre-Tostado F.S., Quevedo-Lopez M.A., The University of Texas at Dallas, US

We report the development of low power ZnO-based inverters. Inverters were evaluated as function of gate dielectric thicknesses and electrically characterized at several power supply voltages. The logic inverters gain increases one order of magnitude [...]

Multifunctional Electrodes Based on MWNTs Sheets and Yarns

Carretero-González J., dela Cruz M.E., Fang S., Ferraris J.P., Baughman R.H., The University of Texas at Dallas, US

Solid-state fabricated carbon MWNTs sheets and yarns exhibit very high electrochemically accessible surface area, which combine with their high electronic conductivity and useful mechanical properties to make these materials attractive candidates for supercapacitor and artificial [...]

Simulation of Constant-Charge Biasing Integrated Circuit for High Reliability Capacitive RF MEMS Switch

Choi K.H., Lee J.B., Goldsmith C.L., The University of Texas at Dallas, US

This paper provides simulation results for a constant-charge biasing IC for capacitive RF MEMS switches to drastically improve reliability. It is well known that there are some forefront issues for RF MEMS switches to be [...]

A 20 µm Movable Micro Mobile

Jeon J., Lee J.B., Kim M-J, The University of Texas at Dallas, US

We present design, fabrication, and characterization of an extremely small (20x14 µm) movable 3D micro vehicle. The micro mobile was fabricated using a combination of focused-ion-beam (FIB) for micro/nano parts production, atomic layer deposition (ALD) [...]

Growth and characterization of CNT Forests using Bimetallic Nanoparticles as Catalyst

Lee B.J., Lee G.S., Lee K.H., Sra A.K., Jang H.-S., Lee B.J., Lee G.S., Lee K.H., Overzeta L., Yang D.J., Lee B.J., Lee G.S., Lee K.H., The University of Texas at Dallas, US

In this poster, we will discuss about a simple efficient way of producing bimetallic FePt, FeCo alloy nanoparticles that are used as catalysts for continuous growth of forests of MWCNTs by PECVD or thermal CVD [...]
