Nanoscale Lithography and Thermometry with Thermal Scanning Probes

Samuel Tobias Howell

Thermal scanning probe lithography (t-SPL) is an advanced lithography technique in which a heated atomic force microscope tip locally modifies a sample material. Due to the nanometer-sized tip apex diameter, t-SPL enables patterning of sub-10 nm structures ...
