Programmed electrophoretic assembly and heterogeneous integration of optoelectronic devices at silicon substrates

Abstract

A novel technique for programmed integration of multiple GaAs based optoelectronic devices that exploits the response of these components to DC electric fields applied in nonaqueous solvents as a means to achieve their field assisted transport and site-selective localization has been developed. Application of the technique to heterogeneous integration of 50 and 80 micron diameter 650 nm emission GaAs based LEDs at silicon substrates is demonstrated.
