    High efficiency monolithic photodetectors for integrated optoelectronics in the near infrared
    (IEEE, 2009) Okyay, Ali Kemal; Onbaşlı, M. Cengiz; Ercan, Burcu; Yu H.-Y.; Ren, S.; Miller, D.A.B.; Saraswat, K.C.; Nayfeh, A.M.
    Monolithic Germanium photodetectors integrated on Si with external efficiency up to 68% at 1550nm and low dark current density 3.2mA/cm2 are demonstrated. The absorption edge red shifted by 47nm corresponding to bandgap energy reduced by 24meV. © 2009 IEEE.
