This collection marks the 30th anniversary of the discovery of high-temperature superconductors. The papers selected highlight some of the advances that have been made to date, both in understanding why these compounds behave in the way they do, and in utilizing them in applications. The papers included in the collection have been made free to read.
Reflectivity curves derived from the proposed dry SAM fit in the Comment . The parameters are those used in the Comment, except (a) SAM layer removed; (b) layer removed; (c) all layers present, but interface width increased from 0.5 to 2 Å—this curve is shifted downwards for clarity. The data points (shown twice) are from our Letter.Reuse & Permissions
