Combining solution processed and vacuum deposited layers in small molecule organic solar cell

Kim Y., Imperial College, UK

In this work the characteristics and mechanisms remarkably affecting efficiency in vacuum deposited small molecule solar cells using pentacene, C60, and BCP and the combination of solution processed and vacuum deposited layers like a P3HT [...]

An Ab Initio Study of CuGaSe2 (001) Surface

Chew S., Liborio L., Harrison N., Imperial College London, UK

The chalcopyrite material CuIn1-xGaxSe2 makes one of the best performing devices for thin film solar cells. Despite this, there is still a lack of understanding of some of the fundamental properties of the material. CuGaSe2 [...]

High dielectric tunability of Ba0.6Sr0.4TiO3 thin film deposited by radio-frequency sputtering

Zuyong F., Nanyang Technological University, SG

Recently, the nonlinear dielectric property of BST thin films has been investigated for the development of frequency agile RF and highper formance microwave tunable devices, which include phase shifters, tunable filters, steerable antennas, varactors, and [...]

The Application of Ansperical Microlens Array on Direct Backlight System

Tsou C., Lai T., Huang C., Chang C., Wu C., Feng Chia University, TW

Today’s liquid crystal displays (LCDs) have to achieve more brightness and better uniformity in a thinner package, especially for the large-sized LCD panels with direct-type LED backlight system. Different reflective and transmissive characteristics managed by [...]

Application of direct growth ZnO nanaotetrapods in field emission device

Zhang Q., Zhang Y., Qi J., Zhang Q., Zhang Y., Liao Q., Ye N., University of Science and Technology, Beijing, CN

In summary, we demonstrate the ZnO nanotetrapod synthesized by a simple vapor phase transport process can be good field emission emitters. The field emission measurement as-synthesized materials reveal that these samples have low turn-on field [...]

Gallium Nitride Nanowire Enhanced High Intensity Discharge Luminance System

Tsai J.T.H., Liao Z.-J., Tatung University, TW

We produce an mercury-free, high efficiency HID lamp with the GaN nanostructure enhancer embedded. These dense GaN nanowires embedded into the HID electrodes can reduce 25% of ignition voltage and enhance the 17% of efficiency [...]

Applications of Memristor Crossbars for Pattern Recognition and Robotics

Mouttet B., George Mason University, US

The presentation will cover applications that I am developing for nanoscale hysteretic resistance materials (i.e. memristors) in pattern recognition circuitry as well as potential applications in robotics and artificial intelligence. Topics will include discussion of [...]

Analog Nanoelectronic Computation: I. Simulation of Dynamical Systems

Schmieder R.W., NanoLogic, Inc., US

We describe here a new paradigm for computation and computer design that has the potential for performance many orders of magnitude higher than conventional digital computers, especially for large-scale simulation of complex systems. The paradigm [...]

Effective Removal Module by Excimer Irradiation Assistance

Pa P.S., National Taipei University of Education, TW

A new design module using an excimer irradiation to assist in micro-electroremoval process as a precise recycle modus for the digital paper of the touch-panel offers a faster per-formance in removing the Indium-tin-oxide thin-films from [...]
