alxian Posted August 14, 2009 Report Share Posted August 14, 2009 I'm trying to find out if like metal based conductors, silicon based polymers warm up when a current is passed through them. If they produce heat alone or if they release any amount of light. Could silicon or a silicon based polymer be used as a filament. Quote Link to comment Share on other sites More sharing options...
freeztar Posted August 14, 2009 Report Share Posted August 14, 2009 Yes, they can produce light. (not sure about heat, but I would imagine so) Optics InfoBase: Applied Optics - Micromachined, Silicon Filament Light Source for Spectrophotometric Microsystems Quote Link to comment Share on other sites More sharing options...
UncleAl Posted August 14, 2009 Report Share Posted August 14, 2009 Silicone is the polymer, -(OSiRR')n-. Silicon is the element. Silicon electronic light emitters are inefficient for the electronic structure of silicon. Single crystal silicon carbide IR and visible thermal emitters are patented. Elemental silicon's low melting point makes it an inefficient black body visible emissive filament. Elemental silicon's transparency to IR makes it a poor IR black body emissive filament (First Law of Thermodynamics). Silicon contracts when it melts, like water ice.
