We report on the molecular beam epitaxial growth and characterization of In(Ga)N nanowires on Si(111) substrates. We also describe the growth and optical properties of InGaN/GaN dot-in-a-wire heterostructures on Si(111) substrates with emission in the green, yellow, and red wavelength range. The design, fabrication, and characterization of In(Ga)N nanowire solar cells and LEDs are discussed. InN p-i-n axial nanowire homojunction solar cells exhibit a promising short-circuit current density of - 14.4 mA/cm2 and an energy conversion efficiency of - 0.68% under 1-sun, AM1.5G illumination. Strong green, yellow, and amber emission has also been achieved from InGaN/GaN dot-in-a-wire LEDs at room temperature.
