Hot-carrier separation in heterostructure nanowires observed by electron-beam induced current

The separation of hot carriers in semiconductors is of interest for applications such asthermovoltaic photodetection and third-generation photovoltaics. Semiconductor nanowiresoffer several potential advantages for effective hot-carrier separation such as: a high degree ofcontrol and flexibility in heterostructure-based band engineering, increased hot-carriertemperatures compared to bulk, and a ge

Band structure and end states in InAs/GaSb core-shell-shell nanowires

Quantum wells in InAs/GaSb heterostructures can be tuned to a topological regime associated with the quantum spin Hall effect, which arises due to an inverted band gap and hybridized electron and hole states. Here, we investigate electron-hole hybridization and the fate of the quantum spin Hall effect in a quasi-one-dimensional geometry, realized in a core-shell-shell nanowire with an insulator co

Living with the memories—parents’ experiences of their newborn child undergoing heart surgery abroad : A qualitative study

Parents of children with a congenital heart defect needing complex heart surgery are at high risk of developing health problems. One can assume that parents whose child undergoes heart surgery abroad will undoubtably face added and unique stressors and health vulnerabilities. The aim of this qualitative study was to explore the transition experiences of parents of children who underwent a complex

Imaging the Thermalization of Hot Carriers after Thermionic Emission over a Polytype Barrier

The thermalization of nonequilibrium charge carriers is at the heart of thermoelectric energy conversion. In nanoscale systems, the equilibration length can be on the order of the system size, leading to a situation where thermoelectric effects need to be considered as spatially distributed, rather than localized at junctions. The energy exchange between charge carriers and phonons is of fundament

A pilot study on the relationship between primary-school teachers’ well-being and the acoustics of their classrooms

Although teachers’ well-being and vocal health are affected by noise, research on classroom sound environment from the teachers’ perspective is scarce. This study investigated the relationship between teachers’ well-being and classroom acoustics. The possible influence of teachers’ age, experience, teaching grade and class size on the relationship was also investigated. In this study, well-being r

Synthesis of Cr(III) Salen Complexes as Supramolecular Catalytic Systems for Ring-Opening Reactions of Epoxides

The synthesis of two conformationally restricted Cr(III) salen complexes, 2 and 3, is described. Together, they constitute a supramolecular hydrogen-bonding catalytic system for the recently reported asymmetric ring-opening reactions of epoxides by a dynamic supramolecular catalyst. The synthesis involves state-of-the art transformations in frontline synthetic chemistry applied to heterocyclic che

Familial associations for rheumatoid autoimmune diseases

Objective: Previous studies have shown a familial component in RA and in some other rheumatic autoimmune diseases (RAIDs), but because of the different study designs the risk estimates for familial risks differ extensively. The objective of this study is to identify familial components for RAIDs. Methods: We collected data on patients diagnosed in Swedish hospitals with RA, AS, PM/DM, SS, SLE and

Familial associations for Addison’s disease and between Addison’s disease and other autoimmune diseases

DESIGN: Addison disease (AD) is a rare autoimmune disease (AID) of the adrenal cortex, presenting as an isolated AD or part of autoimmune polyendocrine syndromes (APSs) 1 and 2. Although AD patients present with a number of AID co-morbidities, population-based family studies are scarce. We aimed to carry out an unbiased study on AD and related AIDs.METHODS: We collected data on patients diagnosed

Risk of invasive breast cancer in relatives of patients with breast carcinoma in situ : a prospective cohort study

Background: Wide implementation of mammography screening has resulted in increased numbers of women diagnosed with breast carcinoma in situ. We aimed to determine the risk of invasive breast cancer in relatives of patients with breast carcinoma in situ in comparison to the risk in relatives of patients with invasive breast cancer. Methods: We analyzed the occurrence of cancer in a nationwide cohor

Low temperature scanning tunneling microscopy and spectroscopy on laterally grown InxGa1-xAs nanowire devices

Laterally grown InxGa1-xAs nanowires (NWs) are promising candidates for radio frequency and quantum computing applications, which, however, can require atomic scale surface and interface control. This is challenging to obtain, not least due to ambient air exposure between fabrication steps, which induces surface oxidation. The geometric and electronic surface structures of InxGa1-xAs NWs and conta
