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.

 

 

Group meetings

For the fall of 2011, group meetings are held Wednesday afternoon at 5:30pm in Baker G57.  The current group meeting schedule can be found here: Group meeting schedule.

 

 

To the new first-year Cornell graduate class:

The Marohn group has up to three openings for graduate students in the Fall of 2011 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 any of the current grad students (contact info in the About Us section), or just stop by the lab to chat with the students.  We are located in Baker 150 (offices) and Baker 146 (main lab).  You can also check out our ongoing projects in the Research section.  In addition, you are always welcome to check out our group meetings.
