Catalytic Growth of N-doped MgO on Mo(001)

Autor: Grob, M., Pratzer, M., Ležaić, M., Morgenstern, M.

A simple pathway to grow thin films of N-doped MgO (MgO:N), which has been found experimentally to be a ferromagnetic d0 insulator, is presented. It relies on the catalytic properties of a Mo(001) substrate using growth of Mg in a mixed atmosphere of

Probing two topological surface bands of Sb2Te3 by spin-polarized photoemission spectroscopy

Autor: Pauly, C., Bihlmayer, G., Liebmann, M., Grob, M., Georgi, A., Subramaniam, D., Scholz, M. R., Sánchez-Barriga, J., Varykhalov, A., Blügel, S., Rader, O., Morgenstern, M.

Publikováno v: Phys. Rev. B 86, 235106 (2012)

Using high resolution spin- and angle-resolved photoemission spectroscopy, we map the electronic structure and spin texture of the surface states of the topological insulator Sb2Te3. In combination with density functional calculations (DFT), we direc

Gundlach oscillations and Coulomb blockade of Co nano-islands on MgO/Mo(100) investigated by scanning tunneling spectroscopy at 300 K

Autor: Pauly, C., Grob, M., Pezzotta, M., Pratzer, M., Morgenstern, M.

Ultrathin MgO films on Mo(100) with a thickness up to 12 ML are studied by scanning tunneling microscopy and spectroscopy at room temperature. The spatial variation of the work function within the MgO film is mapped by field emission resonance states
