The energy band diagrams for three semiconductor samples of silicon are as shown. We can then assert that <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/62b6a2a8a5962021d0be9bcd00e88746-.png" /> (A) sample X is undoped while sample Y and Z have been doped with a 'third group' and a 'fifth group' impurity respectively. (B) sample X is undoped while both samples Y and Z have been doped with a 'fifth group' impurity. (C) sample X has been doped with equal amounts of 'third and fifth group' impurity while samples Y and Z are undoped. (D) sample X is undoped while samples Y and Z have been doped with a 'fifth group' and a 'third group' impurity respectively

X, Y, Z represent an intrinsic, N -type and P -type semiconductors respectively

Q. The energy band diagrams for three semiconductor samples of silicon are as shown. We can then assert that

sample X is undoped while sample Y and Z have been doped with a 'third group' and a 'fifth group' impurity respectively.

sample X is undoped while both samples Y and Z have been doped with a 'fifth group' impurity.

sample X has been doped with equal amounts of 'third and fifth group' impurity while samples Y and Z are undoped.

sample X is undoped while samples Y and Z have been doped with a 'fifth group' and a 'third group' impurity respectively

$X, Y, Z$ represent an intrinsic, $N$ -type and $P$ -type semiconductors respectively
