Problem: Effective Mass

    

Calculate the effective mass tensor tex2html_wrap_inline6061 for electrons in a simple cubic tight-binding band at the center ( tex2html_wrap_inline6063 ), at the face center ( tex2html_wrap_inline6065 ), and at the corner ( tex2html_wrap_inline6067 ) of the Brillouin zone. Discuss the usefulness of the effective mass concept at tex2html_wrap_inline6065 .
