    Abstract : Thermonuclear fusion is a promising energy source for the future. If an economically efficient thermonuclear reactor would be built it has to be a cheap, safe, and highly productive electric power plant, or, a heating plant. READ MORE

  4. 2. Defect Induced Room-Temperature Ferromagnetism in ZnO and MgO Thin FIlms and Device Development

    Author : Mukes Kapilashrami; Lyuba Belova; E Dan Dahlberg; KTH; []

    Abstract : This thesis presents the discovery of defect induced room-temperature ferromagnetism in industrially important ZnO and MgO thin films, and establishes from a systematic study, in both ZnO and MgO films, the unique phenomenon of the sequences of transitions from ferromagnetism to para-, and eventually the well known diamagnetism of the bulk as a function of film thickness. Highly oriented and high quality dense thin films of ZnO and MgO have been deposited by reactive (balanced) magnetron sputtering under different ambience conditions and deposition temperatures.
