摘要： Embodiments of the present disclosure describe a white light illumination system using InGaN-based orange nanowires (NWs) LED, in conjunction with a blue LD for high speed optical wireless communications. By changing the relative intensities of an ultrabroad linewidth orange LED and narrow-linewidth blue LD components, a hybrid LED/LD device achieves correlated color temperature (CCT) ranging from 3000 K to above 6000 K with color rendering index (CRI) values reaching 83.1. Orange-emitting NWs LED are utilized as an active-phosphor, while a blue LD was used for both color mixing and optical wireless communications.

摘要： Methods of direct growth of high quality group III-V and group III-N based materials and semiconductor device structures in the form of nanowires, planar thin film, and nanowires-based devices on metal substrates are presented. The present compound semiconductor all-metal scheme greatly simplifies the fabrication process of high power light emitters overcoming limited thermal and electrical conductivity of nanowires grown on silicon substrates and metal thin film in prior art. In an embodiment the methods include: (i) providing a metal substrate; (ii) forming a transition metal dichalcogenide (TMDC) layer on a surface of the metal substrate; and (iii) growing a semiconductor epilayer on the transition metal dichalcogenide layer using a semiconductor epitaxy growth system. In an embodiment, the semiconductor device structures can be compound semiconductors in contact with a layer of metal dichalcogenide, wherein the layer of metal dichalcogenide is in contact with a metal substrate.

The simultaneous transparency and conductivity are provided by a thin, translucent metal contact integrated with a quartz substrate. The light transmission properties of the translucent metal contact are tunable during epitaxial growth of the nanowires LED. Transparent light emitting diodes (LED) devices, optical circuits, solar cells, touch screen displays, and integrated photonic circuits can be implemented using the current platform.
