The theoretical analysis of the effect of interface confinement on the enhancement of carrier mobility in Si nanowires (SiNWs) is one of the critical aspects in the design and development of high efficiency Si-based optoelectronic devices. Herein, we propose an analytical method for SiNWs under different interface confinements in terms of the atomic-bond-relaxation correlation mechanism and continuum medium mechanics. Moreover, an analytical expression for the relationship between carrier mobility and bond identities is derived and the results are validated with the related experimental measurements. It is found that the size reduction of SiNWs can not only increase the energy bandgap, but also enhance the phonon and surface roughness scattering, thereby allowing for the depression of carrier mobility. Moreover, the underlying mechanism regarding the temperature dependent-carrier mobility in SiNWs with different orientations embedded within Ge coating layers is clarified, which provides a pathway to modulate the transport properties in Si-based nanostructures for desirable applications.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
