Abstract:

Low-resistance ohmic conduction across an epitaxially lifted-off (ELO) thin n-GaAs film and a Si substrate was obtained by attaching the ELO film on the Si substrate coated with a Pd/Ge/Pd multilayer. Good bonding and ohmic contacts to both GaAs and Si were achieved at the same time after annealing. The interface compound formation was studied by secondary ion mass spectroscopy and x-ray diffraction analyses. The ELO technology was used to fabricate an ELO stripe geometry diode laser on Si with the back-side contact on Si substrate. Good laser performance with comparable characteristics as conventional laser diodes on GaAs substrates was obtained.
