Negative bias temperature instability (NBTI) of pMOS structures is a critical reliability concern for modern semiconductor devices. We propose and evaluate an enhanced NBTI model with the following additions to the standard reaction-diffusion (RD) model [1] (a) coupling to the semiconductor device equations to self-consistently include the oxide field, surface hole concentration, charged carrie...

We report that photo-cleaving the corona of block copolymer micelles provides well-defined nanoparticles with surface charges accessible for electrostatic modification.

An alkyl disulfide containing two sulfonate-substituted ferrocenes, 7,8-dithiatetradecane-1,14-di(aminocarbonyl)-bis(1′-ferrocene-1-sulfonic acid), was synthesized and used to form electroactive selfassembled monolayers on gold electrodes. Atomic force microscope (AFM) force curves were employed to measure in situ the change in surface charge as the ferrocene groups were oxidized to compensate ...

The present work examines the conditioning of the least-squares matrix for obtaining potential derived charges and presents a modification of the CHELP method for fitting atomic charges to electrostatic potentials. Results from singular value decompositions (SVDs) of the least-squares matrices show that, in general, the least-squares matrix for this fitting problem will be rank deficient. Thus,...

BACKGROUND Cells exhibit distortion when exposed to a strong electric field, suggesting that the field imposes control over cellular biomechanics. Closed pure lipid bilayer membranes (vesicles) have been widely used for the experimental and theoretical studies of cellular biomechanics under this electrodeformation. An alternative method used to generate an electric field is by electromagnetic i...
