The effect of vacancy induced localized states on thermoelectric properties of armchair bilayer phosphorene nanoribbons

We consider an armchair bilayer phosphorene that is connected to two hot and cold leads from both sides and study the thermoelectric properties of such a system with periodic vacancies at the middle of nanoribbon and in the armchair direction. For this purpose, we first analytically show that by cre...

Description
Summary:We consider an armchair bilayer phosphorene that is connected to two hot and cold leads from both sides and study the thermoelectric properties of such a system with periodic vacancies at the middle of nanoribbon and in the armchair direction. For this purpose, we first analytically show that by creating a vacancy, a localized state is generated around it. Then we demonstrate that in the presence periodic vacancies, a new energy band will be formed in the energy bandstructure, and by changing the distance between the vacancies, the width of the transmission channel and finally the electric power and thermoelectric efficiency can be tuned.
