| 2. | there will be more free electrons than holes in the semiconductor |
| 3. | its resistance is increased |
| 4. | it becomes a type semiconductor |
| 1. | Electrons are minority carriers and pentavalent atoms are dopants. |
| 2. | Holes are minority carriers and pentavalent atoms are dopants. |
| 3. | Holes are the majority carriers and trivalent atoms are dopants. |
| 4. | Electrons are the majority carriers and trivalent atoms are dopants. |
For a type semiconductor, which of the following statements is true?
| 1. | Electrons are the majority carriers and pentavalent atoms are the dopants. |
| 2. | Electrons are the majority carriers and trivalent atoms are the dopants. |
| 3. | Holes are the majority carriers and trivalent atoms are the dopants. |
| 4. | Holes are the majority carriers and pentavalent atoms are the dopants. |
An intrinsic semiconductor is converted into an type extrinsic semiconductor by doping it with:
1. phosphorous
2. aluminium
3. silver
4. germanium
The electron concentration in an type semiconductor is the same as the hole concentration in a type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them.
| 1. | current in type current in type. |
| 2. | no current will flow in type, current will only flow in type. |
| 3. | current in type current in type. |
| 4. | current in type current in type. |
Preparing Types Of Semiconductors for NEET
Types Of Semiconductors is a specific sub-topic that frequently appears in the NEET examination. Understanding the underlying principles and practicing targeted questions is key to mastering this concept.
The questions compiled above are previous year questions (PYQs) directly related to Types Of Semiconductors. Practicing these specific questions helps you understand the difficulty level and the examiner's approach to this topic.
Topic Frequently Asked Questions
Is Types Of Semiconductors a high-weightage topic?
You can refer to the priority and consistency badges at the top of this page. High priority topics should be thoroughly revised multiple times before the exam.
Should I memorize the solutions?
No, it is highly recommended to understand the core concept and methodology behind each solution rather than memorizing them, as exact questions are rarely repeated, but the concepts definitely are.
