| Abstract: | Using the membrane model which is based on brick-wall model, we calculated the free energy and entropy of Gibbons—Maeda dilation black hole due to arbitrary spin fields. The result shows that the entropy of a scalar field and the entropy of a fermion field have similar formulas. There is only a coefficient difference between them. Furthermore, both entropies depend on the degeneracy of the field. |
