Beyond the Bologna and Cheese Metaphor

An interview with Meera Chandrasekhar, Professor of Physics

Meera Chandrasekhar, Professor of Physics at MU, describes herself as “a condensed matter experimentalist,” that is, a physicist who studies a class of materials called condensed matter systems (formerly known as “solids”). Within this class are three types of materials: insulators (Styrofoam, plastic, and rubber), which do not allow electricity to flow; conductors (metals), which do allow electricity to flow; and semiconductors, which “have conductivities in between that of insulators and conductors.” Chandrasekhar has spent most of her research career seeking to understand the special properties of this “in between” class of materials, and she speaks lovingly about how these semiconductors are unusual by virtue of their limited electrical conductivity and their particular response to light.

Quantum mechanics 101

From an interview with Meera Chandrasekhar, Professor of Physics

“As an electron travels around, it keeps bumping into stuff,” Chandrasekhar offers as a simple explanation. “So the behavior of the electron gets defined not just by all the other stuff around it, but by the fact that it is bumping into the edges” of different materials. Quantum mechanics helps to explain the different kinds of behaviors that occur when dealing with very small scales.
