The Crystal Structure of III-V Semiconductor Nanowires: Growth and Characterization

This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. In particular cross-sectional scanning tunnelling microscopy (XSTM) and cathodoluminescence microscopy (CL) were employed to investigate heterost

Romanian grammar: its peculiarities from Indo-European perspectives

This article discusses peculiarities of the Romanian grammar in comparison with other Ind-European languages from historical perspective. It shows that Romanian uniquely preserves older characteristics of Indo-European languages, which makes it look 'an odd-one-out' among other Romance languages.

Polisen i förändring: Intervjuer med de anställda och analys of deras arbetsmiljö

This report is based on 75 in length interviews with employees, both police and civilians, concerning their health, their work environment, leadership and organization. A scale was derived from the interviews and when used together with statistics on turn-over rates and sick leave absences formed a useful tool for police leadership to identify troublesome or potentially troublesome work environmen

A 175uW 100MHz-2GHz inductorless receiver frontend in 65nm CMOS

This paper presents an inductorless ultra-low power frontend for applications such as sensor networks and medical implants. By using a completely inductorless topology the chip area is just 0.017mm2, excluding pads. A real input impedance of 300Ω is achieved with current feedback. Manufactured in 65nm CMOS, it measures more than 17dB gain from 100MHz to 2000MHz while consuming only 175μW from a 0.

Homogenization of dispersive material parameters for Maxwell's equations using a singular value decomposition

We find effective, or homogenized, material parameters for Maxwell’s equations when the microscopic scale becomes small compared to the scale induced by the frequencies of the imposed currents. After defining a singular value decomposition of the non-selfadjoint partial differential operator, we expand the electromagnetic field in the modes corresponding to the singular values, and show that only the
