Abstract

In recent years, significant interest has emerged in the synthesis of magnetically-doped semiconductors. For computing, these materials provide a venue to exploit spin for computation. Direct bandgap spin-doped semiconductors are potential sources for polarized optical emission. In addition, quantum-entangled spins have been proposed as mediators in photon-based quantum communication schemes. In this paper, we discuss the properties of spin-doped ZnO. Mn-doped ZnO demonstrates ferromagnetism at relatively high temperatures as evidenced in hysteretic behavior in the magnetic flux versus field behavior. Transition metal doping was explored via ion implantation. Investigations of group V doping for p-type conduction are also discussed.
