Is there anyone familiar with plotting tight-binding band structures for 2D materials with large unit cells (more than 30 atoms) using Wannier90 ?

I am studying electronic structural features of 2D materials which contain almost more than 30-40 atoms in the unit cell. I think it is more tedious writing direct python scripts like for a 2 atom...

How are hole and electron velocities different from hole and electron mobility?

Because velocities are calculated by the slope of band dispersion while mobility is calculated from the scattering mechanism, can we calculate hole and electron velocities using band slopes in...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Arena simulation - how do i model the following model in ARENA (see description) (new to ARENA)?

Hello, I'm fairly new to ARENA and I have the following problem: I have two queues in which, in each queue, a different order type arrives (both having an arrival rate of exponential 10). Order...
