Semiconductor physics, effective mass calculations, band edge. vs. DOS vs cyclotron resonance

I am trying to understand effective mass for electron carriers in the conduction band as found in experiments. I am using the equations in a simulator. The simulator models power mosfets from -85C to ...

In what pattern does the electrons get emitted from cathode in thermionic emission?

We have structure with an cathode and filament at the center. A cylindrical shaped anode with cavities surrounds the cathode (fig 1). When the cathode get heated the electrons are emitted from cathode ...

How does the hot point-probe test affect p-type semiconductors?

In an n-type semiconductor if you place a hot probe close to a cold metal probe, the average thermal velocity of electrons near the hot probe increases which leads to a net electron motion from the ...

Effect of electron discrete nature on current density

Coulomb’s law states that the current that flows through a wire is proportional to the applied voltage. For sure there are many physical effects (linear and non-linear) that participates in the ...

Theory : High voltage but low current

I read that : A generator products electrons that it sends into wire The electron motion is due to the repulsive behavior between electrons So to increase the voltage (speed of electrons?), ...

What happens when a conductor gains potential, but is not completing a circuit

I asked this on the physics stack initially, but I think it could also be appropriate here. I am not confused about how a conductor gains the same potential as the lead it is connected to (in the ...
