Spark Plasma Sintering is one of the most effective tools in modern sintering history. Since the discovery of superconductivity in MgB 2 , there has been great interest in this atmospheric pressure-based material. In this paper, the effect of sintering temperature on superconduc…

This thesis consists of spectroscopic studies of the electron-doped high temperature cuprate superconductors Pr2−xCe xCuO4−δ (PCCO) and Nd 2−xCexCuO 4−δ (NCCO). Point contact and high barrier tunneling spectroscopies were employed to study the evolution of the superconducting ga…

I introduce the concept of modular materials and give a brief overview of their history and widespread occurrence in many areas of chemistry. I then discuss some of the many applications in which modular materials may find a use and link them to the following chapters. Chapter 1…

Dilute magnetic semiconductors (DMSs) are attractive. They are candidate materials for applications in novel spintronic devices. Because of the giant Zeemaneect in the paramagnetic state, a magnetic eld can be used to manipulate the spin and charge of carriers in DMSs. One possi…
