Abstract

In this paper, we report optoelectronic sensors using conductometric InGaAs/GaAs helical nanobelts. Helical nanobelts improve the unit length responsivity of the photodetector while maintaining a high external quantum efficiency (EQE) per unit length. Nanorobotic assembly and characterization of 3-D helical nanobelts for out-of-plane optoelectronic sensors is shown. High optoelectronic sensitivity is experimentally demonstrated using an optical microscope and from light emitting diodes (LEDs) inside a scanning electron microscope (SEM). A probe-type photodetector was assembled using nanorobotic manipulation and in-situ gold nanoparticle ink soldering.
