A research paper by Associate Professor William King and collaborators at the University of Rhode Island was featured this March on the cover of the journal Nanotechnology. In their article, the researchers described their development of a simple batch fabrication process for making 100 nanometer scale heater/thermometers on silicon cantilevers. The process, which combines photolithography and controlled annealing, produces 100-nanometer-wide heater/thermometers that reach a temperature of 500 degrees Celsius in only 56 microseconds and have a maximum temperature that exceeds 700 degrees Celsius.

Nearly all previous designs that have been proposed for integrating heaters into microcantilevers feature much larger heaters that are in the 1 to 20 micrometer range. Being able to manufacture a nanometer scale heater/thermometers is highly desirable, as such smaller heaters can be used to perform thermal diagnostics of nanomaterials as well as to test the temperature dependence of material properties at the smallest possible scale. King's team is currently working on a number of applications for nanoscale thermal processing. These include nanoscale manufacturing, metrology and materials analysis.
