Welcome to the John Marohn Group webpage!

 

Group Overview

The are two major thrusts to the Marohn group's research. The first is understanding circuits and solar cells that are made from plastics. Here we use custom-built scanned probe microscopes to record 100 nm resolution maps of electrostatic potential, capacitance, photo-generation of charge, and electric field fluctuations in working organic devices. The second thrust of the group's research is developing approaches for imaging single molecules such as, for example, an individual membrane protein. Here the approach is to push magnetic resonance imaging to nanometer resolution by detecting magnetic resonance mechanically, using tiny silicon cantilevers.  Please explore our Research section for details on each project.

 

 

To the new first-year Cornell graduate class:

The Marohn group has up to three openings for graduate students in the Fall of 2009 to work in all areas of ongoing research. The group works at the interfaces between chemistry, physics, biology, and materials science; students from any of these allied fields are welcome. We are seeking students of any background who are fearless about trying new things, are primarily interested in experiment, are self-starters, work well on a team and with external collaborators, work best if given a certain degree of independence, are looking to define new fields, and are looking to gain experience in a wide range of advanced techniques in physical chemistry and nanofabrication.

 

If you are interested in learning more about our work, you can contact John or stop by the lab for more information.  You can also check out our ongoing projects in the Research section, or look up contact information for group members in the About Us section.

 

Our group meetings are always open for perspective members and are held every Wednesday at 4:30 pm in the Baker Laboratory faculty lounge.  Group meeting schedule.
