Boundary Condition Effect on Thermoelectric Coefficients

摘要：

　　Influence of physical boundary conditions on the thermoelectric transportation coefficients has been analyzed starting form Onsager equations.Four boundary conditions have been considered: electric short,i.e,the chemical potential difference is zero;electric open,or electric current free;isothermal,i.e.,no temperature difference;adiabatic,or heat flux free.Four kinds of thermoelectric equations have been derived with different boundary conditions.It was found that the influence of boundary cannot be ignored when figure-of-merit is near and larger than 1.0.This results could be useful in designing thermoelectric device with high performance thermoelectric materials.
