title: Peptide-functionalized semiconductor surfaces: strong surface electronic effects from minor alterations to backbone composition.
abstract: The use of non-canonical amino acids is a powerful way to control protein structure. Here, we show that subtle changes to backbone composition affect the ability of a dipeptide to modify solid surface electronic properties. The extreme sensitivity of the interactions to the peptide structure suggests potential applications in improving the performance of electronic devices.
