<p>[QUOTE=&quot;NorthKorea, post: 1975526, member: 29643&quot;]Am I missing something? I always thought semiconductor grade needs to be 99.99999999% pure, or thereabouts. Also, the 40-54 resistivity values don&#039;t seem inline with the 60 Ohm resistivity typically associated to semiconductor grade Germanium... unless, again, I&#039;m completely misunderstanding the physics behind it.</p><p><br /></p><p>It does seem that 99.9999% 40 Ohm would be really good for mirror coating for high grade telescopes, though. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
