We compare and discuss the two most commonly used electrical characterization techniques for nanowires (NWs). In a novel single-NW device, we combine Hall effect and back-gated and top-gated field effect measurements and quantify the carrier concentrations in a series of sulfur-doped InP NWs. The carrier concentrations from Hall effect and field effect measurements are found to correlate well when
Semiconductor nanowires have many properties which makes them interesting for future electronic devices. The fact that they have very small diameters allow them to combine different III-V materials into heterostructures, and makes it possible to grow them on Si substrates which are the basis of nearly all current semiconductor technology. It also allows them to adopt the wurtzite crystal structure
This paper provides an extensive analysis of the demand for alcohol in terms of total quantity and quantity subdivided into frequency and intensity demand. The analysis compares across alcohol types (beer, wine and spirits), alcohol drinking pattern (average drinker vs. binge drinkers) and also how these decisions differ across gender. The analysis is based on a large sample of cross-sectional dat
The purpose of this paper is to examine how behavioural biases affect consumers’ response to energy-use information provided through smart meters (SM). We take insights from behavioural economics and carry out two real-life experiments with SMs and electricity users. The experiments were conducted in Copenhagen (Denmark) to identify and assess the potential of two economic behavioural biases, sali
This study investigates the impact of childhood health on labor market outcomes. We used type 1 diabetes as an instrument of health because its cause is multifactorial and it is triggered by a complex combination of genetic and environmental components; its incidence is low and unforeseeable for the individual; and its onset may be considered an exogenous health shock. Using data from the Swedish
This essay reflects on issues surrounding the remembrance and teaching of the Holocaust. It was commissioned by the project Living History and the Swedish Prime Minister's Office.
In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length. We are therefore able to investigate friction in th
In this presentation will be given an up-date of the status of epitaxially grown III-V nanowires, from the perspective of growth, processing, physics and applications in the areas of nanoelectronics and nanophotonics
Background Improving knowledge of obstetric danger signs and promoting birth preparedness practices are strategies aimed at enhancing utilization of skilled care in low-income countries. The aim was to explore the association between knowledge of obstetric danger signs and birth preparedness among recently delivered women in south-western Uganda. Methods The study included 764 recently delivered
Together with response time the force of responses to stimuli can provide important clues about cognitive and affective processes. However, while there has been much discussion of factors involved in the accurate measurement of response time (RT), key issues and assumptions in assessment of response force (RF) have been far less studied. Here, hierarchical Bayesian analysis is used to examine the
There is an increasing consensus that individual adaptive capacities are critical to successfully adapt to climate change and achieve sustainable development. However, little is known about adaptive practices, particularly in developed countries. Against this background, this paper investigates the strategies used by Swedish citizens to adapt to (changing) climatic variability and extremes. It off
This chapter provides a synthesis of three earlier published studies (Garmy et al. 2012a; Garmy et al. 2012b; Garmy et al. 2013) (survey I) as well as previously unpublished results from a survey conducted in 2013 among students aged 16 (survey II). Objective: The aim was to investigate the effects of sleep, television use and texting and computer habits on overweight, enjoyment of school and fee
