We present dc and RF characterization of InAs nanowire field-effect transistors (FETs) heterogeneously integrated on Si substrates in a geometry suitable for circuit applications. The FET consists of an array of 182 vertical InAs nanowires with about 6-nm HfO high-gate dielectric and a wrap-gate length of 250 nm. The transistor has a transconductance of 155 mS/mm and an on-current of 550 mA/mm at
Disaster recovery after the Indian Ocean tsunami in 2004 led to a number of challenges and raised issues concerning land rights and housing reconstruction in the affected countries. This paper discusses the resistance to relocation of fishing communities in Chennai, India. Qualitative research methods were used to describe complexities in the debate between the state and the community regarding re
It is usually assumed that musculoskeletal pain is associated with both the physical workload and the psychosocial work environment, as well as with personal and lifestyle factors. This study aims to ascertain the prevalence of musculoskeletal pain in women with varying or different occupational exposures, and to explore the associations between musculoskeletal pain and the occupational and person
The clinical knowledge of factors related to the spread of pain on the body has increased and understanding these factors is essential for effective pain treatment. This population-based study examines local (LP), regional (RP), and widespread pain (WSP) on the body regarding comorbidities, pain aspects, and impact of pain and elucidates how the spread of pain varies over time.
In this work, the nucleation and growth of InAs nanowires on patterned SiO2/Si(111) substrates is studied. It is found that the nanowire yield is strongly dependent on the size of the etched holes in the SiO2, where openings smaller than 180 nm lead to a substantial decrease in nucleation yield, while openings larger than View the MathML source promote nucleation of crystallites rather than nanowi
BACKGROUND: ANCA-Associated Systemic Vasculitis (AASV) is characterized by leukocytoclasis, accumulation of unscavenged apoptotic and necrotic neutrophils in perivascular tissues. Dysregulation of neutrophil cell death may contribute directly to the pathogenesis of AASV. METHODS: Neutrophils from Healthy Blood Donors (HBD), patients with AASV most in complete remission, Polycythemia Vera (PV), Sy
The RF performance of vertical nanowire metal-oxide-semiconductor field-effect transistors in realistic layouts has been calculated. The parasitic capacitances have been evaluated using full 3-D finite-element method calculations, combined with self-consistent Schrodinger-Poisson calculations for the intrinsic gate capacitances. It is shown that a performance comparable to planar FETs can be achie
We report on the synthesis of non-tapered wurtzite (WZ) GaP nanowires by use of in-situ etching and the structural and optical characterization thereof. HCl was evaluated as an in-situ etchant in order to impede the onset of radial growth since the WZ crystal phase in GaP nanowires preferentially grows at relatively high growth temperatures around 600 degrees C, at which strong radial growth typic
Nanostructures have many material, electronic, and optical properties that are not found in bulk systems and that are relevant for technological applications. For example, nanowires realized from III-V semiconductors can be grown into wurtzite crystal structure. This crystal structure does not naturally exist in bulk where these materials form the zinc-blende counterpart. Being able to concomitant
Semiconductor nanowires have attracted considerable attention during the last decade and are considered as an alternative path to extend the road for scaled semiconductor devices. The interest is motivated by the improved electrostatic control in the cylindrical geometry and the possibility to utilize heterostructures in transistor design. Currently, nanowire transistors have been realized both in
Abstract Objective. To examine pregnancy outcomes in relation to different categories of glucose tolerance during pregnancy. Design. Prospective observational cohort study. Setting. Patient recruitment and data collection were performed in four delivery departments in southern Sweden. Population. Women delivering during 2003-2005; 306 with gestational diabetes mellitus, 744 with gestational impair
We report on temperature dependence on the drive current as well as long-term effects of annealing in vertical InAs nanowire Field-Effect Transistors. Negatively charged traps in the HfO2 gate dielectric are suggested as one major factor in explaining the effects observed in the transistor characteristics. An energy barrier may be correlated with an un-gated InAs nanowire region covered with HfO2
To evaluate drug adherence, clinical response and predictors thereof for tocilizumab in patients with RA in routine care based on prospectively collected data from the Swedish biologics register, Anti-Rheumatic Therapies in Sweden.
Cross-sectional studies suggest that premature birth and low birth weight may both be associated with low peak bone mass. We followed bone traits in preterm individuals and controls for 27 years and examined the effects of birth weight relative to gestational age [stratified as small for gestational age (SGA) or appropriate for gestational (AGA)] on adult bone mineral density (BMD). We measured di
Single-shot transients and deep-level transient spectroscopy are used to investigate the origins of capacitance hysteresis in n-doped InAs nanowire/HfO2 capacitors. Capacitance transients with a characteristic time in the order of 100 mu s are attributed to emission from electron traps, located in the oxide film. The trap energy is determined to be in the range from 0.12 to 0.17 eV with capture cr
To analyse 5-year cost-effectiveness of early versus optional delayed acute anterior cruciate ligament (ACL) reconstruction.
We present temperature dependent electrical measurements on n-type InAs/InSb nanowire heterostructure field-effect transistors. The barrier height of the heterostructure junction is determined to be 220 meV, indicating a broken bandgap alignment. A clear asymmetry is observed when applying a bias to either the InAs or the InSb side of the junction. Impact ionization and band-to-band tunneling is m
The aim of this study was to investigate the microvascular responses in the skin, to local heat, iontophoretically administered acetylcholine and to sodium nitroprusside in relation to cardiovascular damage in patients with systemic lupus erythematosus (SLE) and matched controls. We also wanted to examine if the ongoing medication in SLE patients influenced this vascular response. We investigated
Repeated injury of the airway epithelium caused by hyperpnoea of poorly conditioned air has been proposed as a key factor in the pathogenesis of exercise-induced bronchoconstriction (EIB) in athletes. In animals, the short-acting beta(2)-agonist terbutaline has been shown to reduce dry airflow-induced bronchoconstriction and the associated shedding of airway epithelial cells. Our aim was to test t
