Calvin F. Quate joined Stanford University in 1961 as a professor in applied physics and electrical engineering. Throughout his research career, Quate has worked on acoustic amplifiers, interaction of acoustics with semiconductors and acoustic correlators-- all of which have become important fields of research.

Quate’s early research in acoustics led to the invention of the scanning acoustic microscope, which has a resolution exceeding optical microscopes. It can reveal structure in optically opaque or transparent materials in sharp contrast that are not easily seen with optics.

In 1981, Quate read about a new type of microscope able to examine electrically conductive materials. Together with Gerd Binnig and Christoph Gerber, Quate developed a related instrument that would work on non-conductive materials, including biological tissue, known as the Atomic Force Microscope (AFM). AFM is the foundation for modern nanotechnology, and continues to be an important tool for researchers.
