 NANOTECHNOLOGY FOR LIFE™

Intellectual Property

ASG is using the texturing of silicon using metal-enhanced etching to produce silicon nanowire arrays.  


ASG owns the IP for practical solar cell device structures with this type of surface and also owns the IP for silicon nanowires used in Li-ion batteries, microfluidics, lab-on-chip, thermoelectrics, MEMS, and sensors.  The unique capabilities of this technology are the controllability of the height, diameter, and density of the nanowires, uniformity over large surfaces, reproducibility, and production via large scale, low cost industrial processes (wet chemistry at atmospheric pressure).


ASG owns an extensive family of IP in the field of silicon nanowires and their application.
