Welcome to the Menke group at UC-Merced! We are a materials
chemistry group in the chemistry department interested in
new materials for solar cells and batteries.
News
Congratulations to Justin Hujdic for his successful
dissertation defense! He and Somnath will be working at
IBM.
Congratulations to Somnath for his successful dissertation
defense. He will henceforth be known as Dr. Ghosh!
Our lab was recently profiled in Merced’s Downtown Life Magazine. You can
read about our research, or take a
lab tour.
Congratulations to Somnath for publishing his first paper
with our group:
Gold core-Semiconductor shell nanowires
prepared by lithographically patterned nanowire
electrodeposition
This paper describes a low-cost method for preparing arrays
gold nanowires coated with either copper-indium-diselenide
or lead selenide, as well as some of the interesting and
unexpected optical behavior of the nanowires.
Congratulations again to Justin for his second paper:
High-density gold nanowire arrays by
lithographically patterned nanowire
electrodeposition
One of the problems with the LPNE method is that while we
can synthesize nanowires using photolithography and beat
the diffraction limit of light, the photolithography does
dictate the nanowire pitch. This paper describes a method
for preparing arrays of nanowires with a nanowire spacing
that is dictated by electrodeposition, rather than
photolithography.
Our first paper has been published:
Lead Selenide Nanowires Prepared by
Lithographically Patterned Nanowire
Electrodeposition
Lead selenide is a small bandgap semiconductor with
applications in IR detectors and mid-IR lasers, as well as
an interesting model system for studying quantum
confinement effects. Here we describe a scalable process
for preparing large arrays of PbSe nanowires, as well as
their electrical properties.
