    Increase in the Photocurrent in Layers of Ge/Si Quantum Dots by Modes of a Two-Dimensional Photonic Crystal

    It has been found that the introduction of layers of Ge/Si quantum dots in a two-dimensional photonic crystal leads to a strong (up to a factor of 5) increase in the photocurrent in the near infrared range. Th...
