Thin films of -MoGe show progressively reduced Tc’s as the thickness is decreased below 30 nm and the sheet resistance exceeds 100 / . We have performed far-infrared transmission and reflection measurements for a set of -MoGe films to characterize this weakened superconducting state. Our results show the presence of an energy gap with ratio 2 0 /kBTc=3.8 0.1 in all films studied, slightly highe...

Spreading resistance analysis on ultrashallow structures is complicated by the interaction of bevel rounding with geometric effects associated with lateral boundaries. When a spreading resistance probe is stepped from the original sample surface, across the rounded region at the bevel edge and onto the bevel, the resistance increases. Some of the increase is the result of approaching the latera...

BACKGROUND Skin graft is one of the commonly done procedures by plastic surgeons, dermato surgeons and general surgeons. Pain at the donor area is a common complaint by the patient. The skin graft donor site area is usually covered with petrolatum dressing dermatosurgeons. AIM This study was done to compare collagen dressing with petroleum gauze dressing in control of post-operative pain on s...

A novel frequency domain technique for image blocking artifact reduction is presented in this paper. For each block, its DC and AC coefficients are recalculated for artifact reduction. To achieve this, a closed form representation of the optimal correction of the DCT coefficients is produced by minimizing a novel enhanced form of the Mean Squared Difference of Slope (MSDS), for every frequency ...

in this paper, formation of wrinkling in bimetal deep drawing process has been investigated by the analytical, numerical and experimental methods. the effects of width of flange, fillet radii of matrix and punch, clearance of blank holder, contact conditions and relative thickness of two sheets on the number and height of wrinkle waves are studied. clearance and contact conditions have the grea...

Any planar resistor (channel) close to a conducting layer left floating (gate) forms a capacitor C whose thermal voltage noise (kT/C noise) has a backgating effect on the sheet resistance of the channel that is a powerful source of 1/f resistance noise in planar resistors and, hence, in planar devices. This 1/f spectrum is created by the bias voltage VDS applied to the resistor, which is a dist...

This deliverable is performed within the scope of the SURFnet Research on Networking (RoN) project. These deliverables are partly written by students of the University of Twente.

A yield enhanced layout method for maximizing yield of integrated resistor networks with a fixed total area is discussed. This approach incorporates both random variations in the sheet resistance and random variations in the contact resistances. The concept of contact/sheet resistance crossover which gives the crossover between contact-resistance dominance and sheet resistance dominance is deve...

Micro-pattern gas detectors, such as the Gas Electron Multiplier (GEM) and the Micromegas need narrow high density anode readout elements to achieve good spatial resolution. A high-density anode readout would require an unmanageable number of electronics channels for certain potential micro-detector applications such as the Time Projection Chamber. We describe below a new technique to achieve g...
