First Electronic Optical Fibers with Hydrogenated Amorphous Silicon are Developed
A bed of amorphous hydrogenated silicon wires that were prepared in the pores of optical fibers. The wires have been chemically etched out of the optical fiber to reveal them. Scale bar is 100 um. Inset: An array of amorphous hydrogenated silicon tubes deposited in an optical fiber. The optical fiber has been cleaved in half to reveal the array of tubes. The very thin glass walls of the fiber surrounding each tube are largely obscured. Scale bar is 5um. Credit: John Badding lab, Penn State University.
Satellite Images of Nighttime Lights Help Track Disease Outbreaks
