%X We study the electron transmission probability in semiconductor superlattices where the height of the barriers is modulated by a Gaussian profile. Such structures act as efficient energy band-pass filters and, contrary to previous designs, it is expected to present a lower number of unintentional defects and, consequently, better performance. The j-V characteristic presents negative differential resistance with peak-to-valley ratios much greater than in conventional semiconductor superlattices.
