I prefer to use a software that with prepared libraries or graphical interface.

Hello I'm looking for a graphical software to simulate a gas sensor mechanism. I thought "comsol multiphysics" could help me to determine the sensing mechanism of semiconductor gas sensor , but I didn't find any thing about this. I would appreciate you If you recommend an appropriate application...

Hello I have a seminar for my Optic Course in university with this title : Optical Parametric Amplifiers. I searched a lot but I couldn't find why its name "Parametric Amp" I think its about RF parametric amp.. Please if you know why named "parametric" share your knowledge with me. Thanks for...

Thaks for your answer I can't say "perhaps" to Perofessor! With Germanium in high doping impurity can achive 2v zener breakdown. Please help me to find the material and impurity to fabricate a 1v zener diode...

My question was about manufacture a semiconductor! Not about a circuit!

Hello I must complete my research before Saturday... my problem is: how can we fabricate a zener diode with lower than 5.6v zener voltage? a curve in my reference book determine how much doping need to manufacture desirable zener voltage. but the minimum voltage we can achieve is about 2.5v in...
