Carbon Nanotube FET Sensor

Schematic of a carbon nanotube FET sensor functionalized with an antibody to a Lyme disease biomarker protein.  The insulating substrate is shown in pink.  When antigen molecules bind to the antibody, the electrical characteristics of the FET are altered.

The SNO+ Experiment

SNO-plus is a multi-purpose neutrino experiment, located 2km underground in an active nickel mine in Sudbury, Ontario. It is a large liquid scintillator experiment, currently under construction, inheriting most of the detector hardware from the successful SNO experiment.  The Penn SNO-plus group is led by Professor Josh Klein.

 

SDSS Galaxy Survey

The UPenn Fit Catalog provides 2-d galaxy profile fits in several visible bands using SDSS data.  Additional data collected from other sources is provided to facilitate analysis. The catalog is constructed and maintained by Professor Mariangela Bernardi and her group.

 

Topological Insulators

This image shows the valence and conduction bands in the phase transition from topological insulator to conventional insulator with increasing tensile strain.

 

Quintic Calabi-Yau manifold

In superstring theory, the fundamental building block is an extended object, namely a string, whose vibrations would give rise to the particles encountered in nature. In order to solve certain classic problems of unified gauge theories, the 4-dimensional effective theory should be in a space which is a Calabi-Yau manifold of complex dimension 3.
