Magnetism and structure at a vacancy in graphene
M. W. C. Dharma-wardana, Marek Z. Zgierski
The electronic structure, bonding and magnetism in graphene containing vacancies are studied using density-functional methods. The single-vacancy graphene ground state is spin pola…
Metallic behaviour of carrier-polarized C molecular layers: Experiment and Theory
Z. H. Lu, C. C. Lo, C. J. Huang +2
Although C is a molecular crystal with a bandgap E of ~2.5 eV, we show that E is strongly affected by injected charge. In sharp contrast to the Coulomb blockade typi…
Molecular electronics exploiting sharp structure in the electrode density-of-states. Negative differential resistance and Resonant Tunneling in a poled molecular layer on Al/LiF electrodes
Z. H. Lu, M. W. C. Dharma-wardana, R. S. Khangura +2
Density-functional calculations are used to clarify the role of an ultrathin LiF layer on Al electrodes used in molecular electronics. The LiF layer creates a sharp density of stat…
Designing molecules to bypass the singlet-triplet bottleneck in the electroluminescence of organic light-emitting-diode materials
M. W. C. Dharma-wardana, Marek Z. Zgierski
Electroluminescence in organic light emitting diode (OLED) materials occurs via the recombination of excitonic electrons-hole pairs Only the singlet excitons of commonly used OLED…
