Effect of inelastic scattering on the average Coulomb-blockade peak heightin quantum dots - art. no. 033307

The average height of the Coulomb-blockade conductance peaks for chaotic el astic scattering is known to increase by a factor of 4/3 upon breaking time -reversal symmetry. We calculate the temperature dependence of this factor in the regime where the inelastic scattering rate Gamma (in) is greater tha n the mean tunneling rate Gamma (el), which itself is less than the mean le vel spacing a. Comparison to recent experimental data by Folk et al. (Folk, Patel, Marcus, Duruoz, and harris, cond-mat/0008052) demonstrates that Gam ma (in) lies below Gamma (el) and hence also below a, consistent with the l ow-energy suppression of inelastic electron-electron scattering in quantum dots.
