Polysilicon depletion effects show a strong gate length dependence according to experimental p-channel MOS capacitance–voltage ( – ) data. The effect can be influenced not only by gate geometries, but also by dopant profiles in poly-gates. These effects have been modeled and verified using device simulation. Nonuniform dopant distributions in the vertical and lateral direction in the poly-gate ...

Half-cone nanoshell arrays, fabricated by a simple and efficient colloidal lithography method, enable uni-directional liquid spreading on their hydrophilic asymmetric nanostructured surface. The preferred direction of the liquid flow is reversed when the surface is made hydrophobic. Accordingly, poly(N-isopropyl-acrylamide) is polymerized onto the surface for in-site controlling the transition ...

Corynebacterium glutamicum is able to accumulate up to 600 mM cytosolic phosphorus in the form of polyphosphate (poly P). Granular poly P (volutin) can make up to 37% of the internal cell volume. This bacterium lacks the classic enzyme of poly P synthesis, class I polyphosphate kinase (PPK1), but it possesses two genes, ppk2A (corresponds to NCgl0880) and ppk2B (corresponds to NCgl2620), for pu...

The reproducibility of the pull-in voltage of a single side clamped free-standing beam has been investigated for application as a DC voltage reference. A 2 mm long beam has been fabricated in an epipoly process with, at the tip, poly-poly electrodes extending into the axial direction for electrostatic lateral deflection and a combdrive operating in the normal lateral beam direction. The DC volt...

A polymer blend system consisting of polystyrene grafted onto poly (p-phenylene ethynylene) (PS-g-PPE) and poly (styrene-blockisoprene-block-styrene) triblock copolymer (SIS) yields highly polarized emission due to the unidirectional alignment of the PPE molecules. During the roll casting, the triblock copolymer microphase separates and creates unidirectionally aligned PS cylindrical microdomai...

In this study, a glassy carbon electrode was modified potentiodynamically with poly(8-aminonaphthaline-2-sulfonic acid) [poly(ANSA)/GCE] for the detection of norfloxacin (NFN) in tablet formulations and human urine samples. Improvement effective surface area decreased charge-transfer resistance confirmed modification GCE by conductive poly(ANSA) film. The appearance an oxidative peak without re...
