Calculation of Fermi surface orbit integrals using a tetrahedron method. I. Orientation dependence of cyclotron masses in Cu and Au

Abstract

Results of a calculation of cyclotron masses in Cu and Au for five extremal orbits and for the orientation dependence in the planes (110) and (100) are presented. The numerical integration along the orbit over the Fermi surface was performed using a modification of the well known tetrahedron method. The electronic bandstructure of Cu was obtained from a H-NFE-TB calculation. For Au a relativistic H-NFE-TB scheme was used. The theoretical results are compared with experimental cyclotron masses obtained from de Haas-van Alphen investigations.
