substratesuch

Substratesuch is a term used in materials science and related disciplines to describe the systematic search for substrate materials that satisfy predefined criteria for a specific application. The concept centers on identifying surfaces that enable or enhance processes such as epitaxial growth, thin-film deposition, or biointerface compatibility, while minimizing lattice mismatch, chemical incompatibility, or thermal instability. The term is primarily found in German-language literature but is also used in international contexts as a descriptive label rather than a formal standard.

Approaches to substratesuch combine criteria definition, library construction, and screening workflows. Researchers define quantitative requirements for structure, chemistry, mechanical properties, and processing compatibility, then assemble candidate substrates into a library that can be evaluated in silico, in vitro, or in situ. The goal is to narrow down options before committing to expensive synthesis or device fabrication.

Common methods include high-throughput experimental screening, computational screening using density functional theory and materials databases, and machine-learning aided predictions. Characterization of candidate substrates often involves X-ray diffraction, atomic force microscopy, electron microscopy, surface energy measurements, spectroscopy, and in situ monitoring during growth or deposition.

Applications span semiconductor and optoelectronic device fabrication, catalysis, energy storage, sensors, and biomedical implants. Substratesuch informs decisions about substrate material, orientation, passivation, and surface treatment to promote film quality and device performance.

Because substratesuch is not a universally adopted formal term, its usage varies by region and field. It is sometimes discussed as part of substrate engineering or materials compatibility studies, rather than as a standalone discipline.
