1. ### Measuring the electron mobility of a molecule

What I have is a layer of Indium Tin Oxide as the anode, a molecule in between, and gold as the cathode. When I run the IV curve of it, it isnt a linear relationship. The closest way I can approximate the behavior is like sqrt(x) or 1-e^(-x). the slope is constantly changing, so I don't know...
2. ### Measuring the electron mobility of a molecule

Hello PF Let's say I have a device with three layers, A, B, and C, where layers A and C are the anode and cathode. I can measure the IV curves from that device easily. Now lets say I added a fourth layer, D, in between A and B. Layer D interacts with layer B such that it increases it's...
3. ### Strength of induced magnetic field inside an inductor

thanks! also, lets assume I'm using a certain gauge of wire, and I'm wrapping them as close together. would making a longer coil create a stronger magnetic field? or would it only serve to make a longer acceleration area? if B=unI, and im wrapping them to the max tightness along the entire...
4. ### Strength of induced magnetic field inside an inductor

I am trying to make a crude coil gun. I remember that if I run current through a coil of wire, it generates a magnetic field according to the right hand rule. Will the inductance of the coil of wire greatly affect the strength of the magnetic field, or is it mainly due to the strength of the...
5. ### How would you calculate the amplitude of an electromagnetic wave?

oh, can you give me a link to an exact equation? id appreciate it
6. ### How would you calculate the amplitude of an electromagnetic wave?

Would it just be the energy of the wave (i.e. E = hf)?
