3. Consider the following concerning use of single electrontunneling devices at room temperature:

a. The charging energy needs to be larger than the thermalenergy (kT). Calculate the minimum capacitance needed to meet thiscriteria for a single electron.

b. Based on this, calculate the area of a capacitor with thiscapacitance assuming a that the relative dielectric constant is 10and the distance between capacitor plates (d) is 1 nm.

c. Given current lithographic techniques (may require a bit ofresearch on your part) would it be realistic to make capacitorsthis small for room temperature operation of SETs?
