Are Capitalists Green? Firm Ownership and Provincial CO2-emissions in China

China has since the 1980s emerged as one of the world’s largest economies and the main emitter of carbon dioxide. Any attempt to combat global warming at the global level is therefore dependent on the future trajectory of Chinese emissions. In this paper we consider the effect of firm ownership on provincial emissions. The hypothesis is that private firms are economically more efficient than non-p

Atomistic studies of nano-structural mechanical behavior and point defects

The content of this thesis consists of two parts. For the first part, size and crystallographic orientational influence on the elastic properties of bcc nanowires and films have been studied through static molecular simulations. In order to explicitly account for surface effects, the concept of surface free energy has been employed. Comparisons between continuum mechanical calculations and results

Transient electromagnetic wave propagation in laterally discontinuous, dispersive media

This paper concerns propagation of transient electromagnetic waves in laterally discontinuous dispersive media. The approach, used here, employs a component decomposition of all fields. Specifically, the propagation operator that maps a transverse field on one plane to another plane is specified. Expansion of this mapping near the wave front determines the precursor or forerunner of the problem.

Studies of Nanowire Devices Enabled by Advanced Nanofabrication

This thesis explores the possibility of using advanced device geometries and heterostructure engineering to manipulate, control, and study the electrical and optical properties of semiconductor nanowires. The first part of the thesis investigates the use of different gate-all-around architectures for creating new types of gate-controlled nanowire devices, primarily intended for fundamental studies
