Electronic Properties of (Pseudo-) Two-Dimensional Materials

This thesis describes research into the interaction between electrons and various (pseudo) two-dimensional materials. This research is using two approaches: in Chapters 3 and 4 a low-energy electron microscope is used, and in Chapters 5 and 6 transport properties are studied. Chapter 1 introduces the concept of a two-dimensional material. First,...

Source positioning in a large-scale tiny-sensor network of arbitrary topology

To effectively localise a source node in a dense wireless tiny-sensor network with an arbitrary 2D/3D node distribution, a novel approach suitable to describe the hop progress of source-to-sink path in such a system is proposed. In this approach, the network topology is described as a regular lattice and relates the statistical parameters of the...
