3GHr. The stirnuhis duration was 300ns and the profile duration, which corresponds to the time for which the scattering parameters measurements are performed during the stimulus duration, was 25011s. The maximum stable gain MSG was determined under different pulsed conditions at I' ds = 10V (Fig. 4). At room temperature in class B for the quiescent hias point, the MSG was -4dB. If the device wa...

C60 bis-adduct containing a mixture of regio-isomers with different LUMO energy levels and steric geometries could greatly affect the morphological and bulk properties. To investigate the regio-isomer effect on solar cell performance, we have successfully designed and synthesized a regio-selective 4-acetatephenyl-4'-methylphenylmethano C60 bis-adduct (S-APM-CBA) by "tether-directed remote funct...

We present an approach for trapping cold atoms in a 2D optical trap array generated with novel 4f filtering scheme and custom transmission mask without any active device. The can be used to generate arrays of bright or dark traps, both simultaneously single wavelength forming two-species traps. demonstrate the design by creating 1225 sites, where Cs are loaded into regions near-zero intensity a...

In this paper, we have investigated the effect of a single Grain Boundary (GB) on the performance of decananometer-scale Thin Film Transistors (TFTs) by using the calibrated energy balance transport model and a continuous trap state distribution at the GB. We have found that the GB potential barrier suppresses the subthreshold slope and leakage current in devices, where the DIBL effect and punc...

We have been using BG-Sentinel (BGS) traps to monitor populations of Aedes albopictus as part of an area-wide project for management of this species. Although BGS traps are very effective for collecting adult Ae. albopictus, the device is expensive and must be properly maintained to be effective. The trap also poses a challenge for mosquito control personnel because secure locations free from t...

We present a novel technique for measuring the characteristics of a magneto-optical trap (MOT) for cold atoms by monitoring the spontaneous emission from trapped atoms coupled into the guided mode of a tapered optical nanofiber. We show that the nanofiber is highly sensitive to very small numbers of atoms close to its surface. The size and shape of the MOT, determined by translating the cold at...

The kinetics of the flux of a charged macromolecular solution through an environment of changing geometry with wide and constricted regions is investigated analytically. A model device consisting of alternating deep and shallow slits known as an "entropic trap" is used to represent the environment. The flux is supported by the external electrostatic field. The "wormlike chain" model is used for...

A simulation has been performed to reveal the detailed dynamics and statistical behavior of a Maxwell demon of the simplest kind, a trap door held over by a spring inside a box filled with gas molecules. The role of such a demon can be controlled by tuning Smoluchowski's fluctuations. When the demon is in thermal equilibrium with the rest of the system, it fails to function as designed, and whe...

We report the first demonstration of the axialization of laser cooled ions in a Penning trap. Axialization involves the application of a small radial quadrupole drive which couples the cyclotron and magnetron motions. This enhances the laser cooling, allowing tighter confinement of the ions to the central axis of the trap than is otherwise possible. Using an intensified charge-coupled device (I...

A low noise amplifier has been designed using a 2SK117 N channel J-FET as the input device in a cascode [1] configuration. Noise measurements on this amplifier yield a low frequency noise current of 0.25 fA/Yfu and a voltage noise of less than 1.2 n V NHz in the 500 Hz to 50 kHz region. Bloyet et al. [2] suggest a figure of merit of the product of the noise voltage and current as being appropri...
