plz hlp Tunneling An electron of energy E = 2 eV is incident on a barrier of width L = 0.61 nm and height Vo-3 eV as shown in the figure below. (The figure is not drawn to scale.) 1) What is the probability that the electron will pass through the barrier? The transmission probability is 0 SubmitHelp 2) Lets understand the influence of the exponential dependence. If the barrier height were decreased to 2.8 eV (this corresponds to only...
A beam of electrons with 100 eV of energy reach a barrier of height 100.5 eV and width 1 pm. If 10 mA of current is reflected off the barrier, what was the incident current of the beam?

2. An electron with energy E= 1 eV is incident upon a rectangular barrier of potential energy Vo = 2 eV. About how wide must the barrier be so that the transmission probability is 10-37 Electron mass is m=9.1 x 10-31 kg. (Hint: note the word "about". A quick sensible approximation is accepted for full credit. The exact calculation is feasible in an exam, but long and perilous - avoid at all costs.]
Consider a traveling (electrons) wave moving in the +x direction approaching a step barrier of height 1 eV; that is V = 0 for x < 0, V = 1.0 eV for x ≥ 0. For x < 0, there will be both the traveling wave in the +x direction. For x ≥ 0, only a solution corresponding to motion in the +x direction exists. By solving the Schrödinger wave equation in both x < 0 and x ≥ 0...

Electrons are fired at a rectangular potential energy barrier, once every 197 ms. If the barrier is 2.55 nm thick and has a height that exceeds the energy of the incident electrons by exactly 537 meV, how long on average would you expect to wait for one electron to pass through the barrier? Electrons are fired at a rectangular potential energy barrier, once every 197 ms. If the barrier is 2.55 nm thick and has a height that exceeds the...
You have a double barrier structure where Barrier 1 that is to the left is 1 nm thick, and 2 eV high. Attached to it is barrier 2 that is to the right, which is also 1 nm thick, but 1 eV high. An electron is incident from the left with energy 0.5 eV. Calculate the tunneling probability.
