A method to optimize the focusing quality of integrally gated CNT field- emission ( FE) devices by combining field- emission modeling and a computational intelligence technique, genetic algorithm ( GA), is proposed and demonstrated. In this work, the e- beam shape, as a characteristic parameter of electron- optical properties, is calculated by field- emission simulation modeling. Using a design tool that combines GA and physical modeling, a set of structural and electrical parameters for four FE device groups, including double- gate, triple- gate, quadruple- gate and quintuple- gate type, were optimized. The resultant FE devices exhibit satisfactory e- beam focusabilities and the extracted parameters with the best performance for each type of FE device were represented to be fabricated by a VLSI technique. The GA- based automatic design parameter extraction will significantly benefit the design of integrated electron- optical systems for versatile vacuum micro- and nano-electronic applications.

In this paper we report the observation of enhanced field emission properties from thiolated multi-wall carbon nanotubes ( MWCNTs) produced by a simple and effective two- step chemical surface modification technique. This technique implements carboxylation and thiolation on the MWCNTs synthesized by microwave plasma chemical vapor deposition ( MPCVD) on the flexible carbon cloth substrate. The resulting thiolated MWCNTs were found to have a very low threshold field value of 1.25 V mu m(-1) and a rather high field enhancement factor of 1.93 x 10(4), which are crucial for applications in versatile vacuum microelectronics.
HIGH-VOLTAGE TOLERANT POWER-RAIL ESD CLAMP CIRCUIT

A high-voltage tolerant power-rail ESD clamp circuit is proposed, in which circuit devices can safely operate under the high power supply voltage that is three times larger than their process limitation without gate-oxide reliability issue. Moreover, an ESD detection circuit is used to effectively improve the whole ESD protection function by substrate-triggered technique. Because only low voltage (1*VDD) devices are used to achieve the object of high voltage (3*VDD) tolerance, the proposed design provides a cost effective power-rail ESD protection solution to chips with mixed-voltage interfaces.
Interacting antiferromagnetic droplets in quantum critical CeCoIn5

The heavy fermion superconductor CeCoIn5 can be tuned between superconducting and antiferromagnetic ground states by hole doping with Cd. Nuclear magnetic resonance data indicate that these two orders coexist microscopically with an ordered moment similar to 0.7 mu(B). As the ground state evolves, there is no change in the low-frequency spin dynamics in the disordered state. These results suggest that the magnetism emerges locally in the vicinity of the Cd dopants.

Dielectric confinement effect in ZnO quantum dots embedded in amorphous SiO2 matrix

The dielectric confinement effect on the blue shift Delta E-g(a) of the ZnO quantum dots (QDs) embedded in the SiO2 matrix is evaluated by applying a multi-shell two-electron system model. The experimental measurement and the calculations of various dielectric structures indicate that the composite matrix structure provides a better estimation of the blue shift of the ZnO QDs-SiO2 system than the multi-shell structure. The proportionality factor x defined in this work exhibits a dependence of the dielectric confinement energy on the specific dimension ratio (the b/a ratio) and the dielectric constant epsilon(matrix) of the outer matrix. The result of the calculation also shows the limit of the two-electron system in estimating the ground-state energy of samples with high dot density. However, the correlation shows the existence of the strong dielectric confinement effect in ZnO QDs-SiO2 thin films and allows a better understanding of the semiconductor QDs-dielectric systems.
