We present a detailed analysis of the light absorption in the coaxial nanowire (NW) of Si core and nonabsorbing dielectric shell which has great potential in solar cells. We have calculated the absorption efficiency within the framework of the Lorenz-Mie light scattering theory to investigate the effects of the core radius, the shell thickness, and the shell refractive index on the light absorption. We have found that the photocurrent can be enhanced up to ~135% for the coaxial NW of the core radius of 150 nm by tuning the shell thickness and the shell refractive index, as compared to Si NW..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
