Nanocalorimetry is a technique developed by Leslie H. Allen's group at the University of Illinois at Urbana-Champaign. I was part of this group as a postdoc in 1999-2000 and then started developing the technique with my students at the Université de Montréal to look namely at damage annealing of low-energy ion-implanted silicon.

Nanocalorimetry is a thin-film equivalent of Differential Scanning Calorimetry (DSC) that can measure the heat associated with reactions or transformations occurring in ultra-thin films, that is, layers of the order of a monolayer or less. It is thus a valuable tool to investigate in situ the evolution of thin-films and nanostructures from a thermal point-of-view.

Recently, our group successfully developed a nanocalorimeter comprising a thin layer of mono-crystalline Si on its surface. This device opens the door for calorimetric measurements to be made on a pure, atomically ordered, and well documented surface. This includes measuring the heat exchanges during the initial phases of thin layer growth, the formation of self-assembled nanostructures of semiconductors and organic materials, solid-state reaction in ultra-thin films, catalytic processes, etc.
