pss - taking legacy to the future

Dear readers, 2016 has a special anniversary coming up for physica status solidi (pss): Its most‐ever‐cited article “Optical Properties and Electronic Structure of Amorphous Germanium” by J. Tauc, R. Grigorovici, and A. Vancu (then Prague and Bucharest) was published half a century ago [1]. Printed about two months after receipt of the manuscript on June 1st 1966, it is a witness of the impressively fast publication times of pss back then. The article went online 40 years later in 2006, when Wiley had the pre‐internet‐era content scanned. Citations (right axis) and cumulative citations (left axis) to “Optical Properties and Electronic Structure of Amorphous Germanium” by J. Tauc et al., pss (1966) [1] versus year (Data from Web of Sci‐ence SCI, Dec 2015). Beyond the reach of contemporary journal‐usage metrics, it has been collecting citations throughout 50 years, and recently we even saw a pronounced acceleration due to renewed interest in amorphous materials, with groups analyzing and developing the method proposed by Tauc et al. further [2]. pss proudly continues to provide, promote, and safeguard this valuable piece of information, and to accompany it through the changing times of its lasting legacy for the solid state physics research community. All the while, we are working with our authors, reviewers, board members, and guest editors to add content to the journal that has the potential for a similarly impressive career in scientific literature. Much of pss ' most interesting content is attracted by specially compiled, topical publications in collaboration with guest editors these days, and we can mention only a few of them here. Prominently in 2015, pss leaned in on the recent physics Nobel Prize topic again with a double issue on Nitride Semiconductors [3], and also the January issue of pss (b) in 2016 is dedicated to the specific challenges of Polarization‐Field Control in Nitride Light Emit‐ters [4]. Regarding long‐lasting topics we should mention the “20 Years of Science for Diamond” issue in pss (a) [5], and on the contemporary device physics line both “Transparent Conductive Oxides – Fundamentals and Applications” [6] and the issue dedicated to “Advanced Materials and Nano‐ technology for Photovoltaics” [7]. Reflecting the intense activity in the field and its impact on the world energy economy, photovoltaics based on inorganic as well as organic electronics have been increasingly prominent throughout the pss journal family, also resulting in t
