Answer (Detailed Solution Below)
Charge Neutrality Question 1 Detailed Solution
Charge on an electron is 1.602 x 10-19 C.
Charge:
- There are two kinds of charge, positive and negative.
- Like charges repel, unlike charges attract.
- The positive charge comes from having more protons than electrons.
- A negative charge comes from having more electrons than protons.
- A charge is quantized.
- A charge is conserved.
q = n e
q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19 Coulombs.

Charge Neutrality Question 4:
A Ga – As LED has refractive index of 3.6 and is surrounded by air (μ = 1). If the bandgap of Ga – As is 1.43. Then out of 500 photons generated in Ga – As, The number of photons emitted out of the specimen are _____
Answer (Detailed Solution Below) 9
Charge Neutrality Question 4 Detailed Solution
Concept:
The external quantum efficiency is given by the relation:
\({η _{ext}} = \frac{{η_{a}^2}}{{4η _s^2}}\)
ηs = Refractive index of the LED
Calculation:
ηs = 3.6
ηa = 1
\({η _{ext}} = \frac{{1}}{{4(3.6)^2}}\)
ηext = 0.0193
Out of every 100 photons generated in Ga – As, only 1.93 are emitted out of the specimen.
∴ for 500 photons → 9.5 will be emitted.
Taking the greatest integer value, we get:
[9.5] = 9
Charge Neutrality Question 5:

i) N-well process
ii) P-well process
iii) Twin well process
