Question:medium

When a semiconductor is doped with pentavalent impurities, the Fermi level (at moderate temperatures) lies :

Show Hint

Pentavalent = n-type = extra electrons = Fermi level pushed UP towards the Conduction Band (near the donor level). Trivalent = p-type = extra holes = Fermi level pulled DOWN towards the Valence Band (near the acceptor level).

Updated On: Jul 31, 2026

Exactly between conduction and valence band
Between donor level and bottom of conduction band
Between acceptor level and top of valence band
Between donor level and top of valence band

In an oligopolistic market, firm i and firm j have constant marginal cost = c for an identical good. They compete to set prices Pi and Pj. The demand for total market demand Q, where if \(P_i > P_j\), the demand for firm i is 0. If \(P_i < P_j\), the demand for firm i is Q. If \(P_₁ = P_j\), then they share the market equally and hence the demand for firm i is \(\frac{Q}{2}\). In equilibrium, the prices of firms i and j are:

In the table below, firm 1 and firm 2 can cooperate to share market profits or compete with each other. The figures in the cells represent the profits in crores of INR. They can either cooperate with each other where they share INR 10 crores equally. Alternatively, they can compete, which lowers the market output to INR 4 crores, which they share equally. If one of the firms competes while the other cooperates, the former obtains INR 10 crore of profit while the other makes zero profit. In equilibrium, firm A and firm B should respectively:

Firm 2	Cooperate	Compete
Firm 1	5, 5	0, 10
Compete	10,0	2, 2
