In the single electron transistor, to achieve Coulomb blockade,
it is necessary that the tunnel barrier of the system is much
higher than the quantum resistance Rt. Calculate Rt

Topic 6. One transistor amplifier (BJT)
1. Design a single transistor amplifier (BJT) with appropriate
coupling and bypassing capacitors. You can use the examples from
the book or homework, but need to change the parameters values
.
2. Draw the DC equivalent circuit and find the Q point. Draw the
AC equivalent circuit and find parameters of your full amplifier
circuit (gain and input resistance) .
3. Simulate the FULL amplifier circuit in DC state (you cannot
use DC operating...
an electron goes from a Betatron accelerator with energy 5 Mev
into Copper barrier.
calculate :
1- at which distance inside the barrier the electron will stop
?
2- as a resultant to this reaction if you detected an emission
of a X-Ray , what do you call this rays ?and what it's emitted
ratio from electron energy ?
( use drawing as possible )
a) An electron with 10.0 eV kinetic energy hits a 10.1 eV
potential energy barrier. Calculate the penetration depth.
b) A 10.0 eV proton encountering a 10.1 eV potential energy
barrier has a much smaller penetration depth than the value
calculated in (a). Why?
c) Give the classical penetration depth for a 10.0 eV particle
hitting a 10.1 eV barrier.
Determine the carburizing time (in s) necessary to achieve a
carbon concentration of 0.44 wt% at a position 1.8 mm into an
iron-carbon alloy that initially contains 0.031 wt% C. The surface
