Answer #1

1)When we remove electron from neutral atom the atom become ionized

So answer is right

2)Conductivity of a semiconductor is

\sigma=en_i(\mu_h+\mu_e)

Where h and e correspond to hole and electrons

So answer is right

3)Conductivity always a opposite property of resistivity

So answer is right

4)So semiconductor conduction band is more energy than valance band

So answer is right

5)Diffusion only occurs due to concentration gradient

So answer is right

    Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral gaseous atom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an electron requires energy. The process is endothermic, and so ionization energies have a positive value. The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X++e− The amount...
