Application of dopant segregation to metal-germanium-metal photodetectors and its dark current suppression mechanism
H. Zang, S. J. Lee, W. Y. Loh, J. Wang, M. B. Yu et al.
We report the mechanism of dopant-segregation (DS) technique as applied in metal-germanium-metal photodetectors (MGM-PDs) for dark current suppression. Photodetectors with various dopant-segregation strategies were designed, fabricated, and characterized. Results show that asymmetric MGM-PD, with n- ... [Appl. Phys.
