The paper studies the drought resistance and performance of five ground covers (Sedumlineare, Sedumlineare dasiaPu Fupsila, Sedumelatinoides, Zephyranthescandida, Ophiopogonjaponicus) under drought-stress through the testing of artificial climatic cabinet. We choose soil moisture content, relative water content of leaves, relative electric conductivity, chlorophyll, SOD, malondialdehyde (MDA),...
Continuous scaling, necessary for enhanced performance and cost reduction, has pushed existing CMOS materials much closer to their intrinsic reliability limits, forcing reliability engineers to get a better understanding of circuit failure. This requires that designers will have to be very careful with phenomena such as high current densities or voltage overshoots. In addition to the reliability issues,...
Transconductance (gm) enhancement in n-type and p-type nanowire field-effect-transistors (nwFETs) is demonstrated by introducing controlled tensile strain into channel regions by pattern dependant oxidation (PADOX). Values of gm are enhanced relative to control devices by a factor of 1.5 in p-nwFETs and 3.0 in n-nwFETs. Strain distributions calculated by a three-dimensional molecular dynamics simulation...
The stability of monolithically integrated copper (indium, gallium) (selenium, sulfur) (CIGS) based thin film solar cells on glass were evaluated as a function of highly accelerated stress testing. Mini-modules exposed to high humidity (85°C and 85% RH) had a dominant failure mechanism involving increased resistance in the ZnO:Al transparent conducting oxide. Under Dry heat (85°C and 0% RH) performance...
This paper presents a structural health monitoring system for monitoring, with reduced visual impact, one historical building structure. The system is based on fiber Bragg gratings and comprises 19 displacement sensors and 5 temperature sensors. All the sensors were custom made according to the monitoring points' characteristics. The results obtained over the first year of monitoring are presented...
Al (1% Si) electromigration in narrow stripes was studied by means of MFT and resistometric methods. For very narrow stripes no correlation could be found between the variation of resistance and the end of life. A simple model was developed to explain the observed small resistance variation.
