Nanoscience for Large-Area Devices

Over the last years we have explored semiconductor deposition methods that allow an
inexpensive nano-structuring and are, at the same time, suitable for large-area
applications, such as solar cells, displays, and sensors. We found that for many
semiconductor compounds electrodeposition offers useful low-temperature processes
that can produce high-quality nano-materials in templated and unconfined growth
regimes. Here we will give a comprehensive review on first successful results in the
fabrication of a novel hetero-junction solar cell, a vertical nano-wire field-effect
transistor and a nano-wire LED. While all of these devices are in an early development
stage, their successful operation clearly indicates that nanoscience will have
considerable positive impact in large-area applications. Future trends will also be
discussed.
Bio: Professor Koenenkamp has received his MS and PhD degrees from Tulane University in Physics.
He served as a visiting Professor at Princeton as well as the Istituto Superior Technico, Lisbon, Portugal.
In 1985, he started a company "Phoenicon GmbH", Semiconductor Testing Equipment Co., in Berlin,
Germany. He has been at PSU since 2002.
This NECP Seminar is jointly sponsored by the NECP program, by the CeNSE and the
Departments of Electrical and Computer Engineering
