Is it possible to consider the dependence for resistance base region of a bipolar transistor (vertical or lateral structure, NPN or PNP) by mechanical deformation, as the dependence for region of the integral resistor based by the p-n junction?
What does the color of a spiro-ometad film indicate? I got purple, green, red, even black color of the spiro film. Is there anything we can get from the preliminary color analysis(e.g. oxidation...
