Photophysics of GaSe/InSe nanoparticle heterojunctions

Article Abstract:

Static and time-resolved absorption and emission spectroscopies are used to study the photophysics of mixed aggregates of GaSe/InSe nanoparticles. The results have shown that GaSe/InSe interfaces form heterojuctions and display photoinduced direct charge transfer from the GaSe valence band to the InSe conduction band, thus resulting in the electrons and holes being localized separately in these two types of nanoparticles.

Electron and hole intraband spectroscopy of GaSe nanoparticles

Article Abstract:

A study of the transient absorption spectroscopy of GaSe nanoparticles is presented. The time resolved absorption and absorption polarization measurements made on 4,6, and 8 nm particles with simple, effective mass quantum confinement model allows assignment of the observed transient absorption spectrum.

High-density arrays of InGaN nanorings, nanorods, and nanoarrows fabricated by a template-assisted approach

Article Abstract:

Dense arrays of InGaN nanostructures with controllable sizes and morphologies were fabricated by selective area growth using nonporous templates. The results showed that the template-assisted approach was versatile and it can be extended to fabricate multilayered nanodots and nanoheterojunction arrays.
