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.
