Conservation Biology, Volume 32, Issue 3, Page 660-671, June 2018., 2018 Abstract Habitat loss is a key driver of biodiversity loss. However, hardly any long‐term time series analyses of habitat loss are available above the local scale for finer‐level habitat categories. We analysed, from a long‐term perspective, the habitat specificity of habitat‐area loss, the change in trends in habitat loss since 1989 (dissolution of ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...
