About this Research Topic
The aim of this Research Topic is to understand the interplay of fundamental properties of solids on the nanoscale with coherent structural dynamics of the crystal lattice. Nanoscale physics refers to physical properties of nanostructures, e.g. the elastic, thermal or structural parameters. It specifically includes both applied and fundamental problems. Examples are actuation or motion control on the nanoscale or the coupling of strain fields to other phenomena, e.g. magnetism or ferroelectricity, respectively. These issues can be tackled and solved using tailored strain fields which may be generated statically during growth or dynamically, e.g. by laser excitation. We refer to the functional generation and application of coherent strain waves as Straintronics. It is the logical continuation of strain engineering and of acoustic spectroscopy starting with classical ultrasonics and leading to today’s ability to generate coherent strain waves on ultrashort time- and length scales using photoacoustics and nanophononics. The idea is to generate synergies through interaction of hitherto separated scientific communities.
We welcome contributions combining the fields of nanostructure physics and nanophononics. Nanostructure physics contributions should discuss problems and solutions regarding strain related phenomena of nanostructures or devices on a fundamental or applied level. Examples are the physics and applications of MEMS/NEMS, sensors, microfluidics, catalysis and others. Nanophononics and photoacoustics contributions should aim for presenting capabilities and potential applications for functional analysis or control of nanostructures. Examples are deformations in thin films and nanoparticles, linear and nonlinear phonon dynamics, strain tailoring and others.
