“…So lithium atoms are kept in the surface-adsorbed positions by the high potential barriers. It is worth noting that the barriers of migration under the surface are lower and are comparable with the migration barriers in bulk silicon, obtained from theoretical calculations (0.85 eV for a cubic silicon supercell containing 64 atoms) and experiment (0.8 eV [13]). …”

“…In this process, the change in volume causes large mechanical stresses and, consequently, a break-up of the crystal [8][9][10][11]. In addition to this, silicon has a low diffusion coefficient for lithium ions [12,13]. These limitations impede application of bulk silicon in modern Li-ion batteries.…”

“…However, the actual time response of the actuator system has to be tested experimentally, as this also depends on the current density the material can withstand. A significant doping of the waveguide with Li can be neglected since the diffusion and solubility of Li in crystalline Si is very low at room temperature. , …”

A new approach for an optical actuator system based on mixed ionic–electronic conductor materials is proposed. The system actuates on light propagating in a waveguide implemented on a photonic integrated circuit by electrochemically changing the composition of the MIEC material, using the characteristic dependence of the optical properties upon stoichiometry. To realize this actuator, a multilayer stack was sputtered and characterized forming a battery-like system where ions reversibly travel from a Li-ion source to a Li x V2O5 layer, producing the desired change of the optical properties. Modal field FEM simulations were carried out to estimate the influence of the formed actuator on a waveguide fundamental mode implemented on the silicon on insulator platform. The time resolution of the actuator is estimated solving the diffusion profile of Li inside the Li x V2O5 coating and its evolution with time. Through simulations and measurements, promising results for a potential actuator system are shown, like small device length (<20 μm), low power consumption (∼10 pW per switch), reversibility, and long time stability.

The surge in advancing the materials science of solid-state reactions for nanoscale contacts to advanced semiconductor devices necessitates a comprehensive dissemination and discussion on recent progress. The objective of this work is to review the notable developments in compound and alloy contact formation to nanoscale nanowire channels made of germanium, silicon, and their heterostructures, and to develop a unifying framework for understanding the significantly distinct reaction behaviors from those commonly observed in bulk. The Ni-based compound and alloy contacts are used as a platform to highlight the size-relevant, thermodynamic, and kinetic differences, and their key material, reaction, and electronic parameters and properties are summarized. Special attention is given to the interplay between the compound/alloy contact structure and the resultant electronic properties.
