Room temperature molecular resolution nanopatterning of cyclopentene monolayers on Si(100) via feedback controlled lithography

Hunter J. Karmel and Mark C. Hersam

Molecularly precise nanopatterning is demonstrated for a saturated organic monolayer on the Si(100) surface using room temperature ultra-high vacuum scanning tunneling microscopy. In particular, feedback controlled lithography enables the clean desorption of individual molecules from a highly-orde ... [Appl. Phys. Lett. 102, 243106 (2013)] published Tue Jun 18, 2013.

The real role of active-shell in enhancing the luminescence of lanthanides doped nanomaterials

Fei Wu, Xiaomin Liu, and Xianggui Kong et al.

Although it is widely recognized that doping sensitizers in the shell can improve significantly the luminescence of lanthanides doped nanocrystals, lack of an unambiguous picture of relevant luminescence enhancement mechanism seriously hinders the optimization of this approach. In this work, the c ... [Appl. Phys. Lett. 102, 243104 (2013)] published Tue Jun 18, 2013.

Formation of non-equilibrium Fe-Au solid solutions in nanoclusters

P. Mukherjee, Lin Zhou, and M. J. Kramer et al.

Fe-Au nanoclusters ranging in composition from ∼33 to 79 at. % Fe were prepared by inert gas condensation. Resulting phases were single crystalline solid solutions for all compositions with significant defects present. The as-deposited clusters formed in a bcc structure for Fe content >65 at. % an ...

Evidence of percolation related power law behavior in the thermal conductivity of nanotube/polymer composites

B.-W. Kim, S.-H. Park, and R. S. Kapadia et al.

A power law relation for the thermal conductivity, indicative of percolation, is reported through measurements on carbon nanotube/polymer composites. Our results contradict earlier assertions and indicate that synthesis methodologies may be adapted to facilitate such behavior. Consistent modeling ... [Appl. Phys. Lett. 102, 243105 (2013)] published Tue Jun 18, 2013.
