• Cross-field electron heat diffusion due to thermally excited high frequency electrostatic waves propagating almost perpendicular to the magnetic field is studied using a two-and-one-half-dimensional simulation code. It is shown that the electron heat diffusion coefficient D_H is an order of magnitude greater than the electron self-diffusion coefficient D_P, which is essentially collisional. The characteristic feature of wave transport is observed, namely an increase of D_H with increasing values of the characteristic temperature scale length L_X. The heat diffusion coefficients D^"_H and D^<⊥>_H for the parallel and perpendicular temperatures (D_H≃D^"_H + D^<⊥>_H) show quite different magnetic field scalings since D^"_H is due to ion modes while D^<⊥>_H arises from electron modes. This is also confirmed by treating the ions as an immobile background.
