Flash sample heating for scanning tunneling microscopy: Desorption of 1-octanethiolate self-assembled monolayers in air

The authors have developed a method of performing scanning tunneling microscopy experiments with a sample that can be controllably heated and quickly cooled. Temperatures in excess of 100 °C are achievable, and the same scanning area can be imaged multiple times before and after repeated heating cyc...

Description
Summary:The authors have developed a method of performing scanning tunneling microscopy experiments with a sample that can be controllably heated and quickly cooled. Temperatures in excess of 100 °C are achievable, and the same scanning area can be imaged multiple times before and after repeated heating cycles. This opens up for study any physical process or chemical reaction where the reactants, products, and/or intermediates can be kinetically trapped on a conductive surface at room temperature. As a demonstration of this approach, the authors have investigated desorption from 1-octanethiolate self-assembled monolayers on Au(111).
