NEET 2026 Physics Semiconductor Electronics Questions

Use this page to connect the official 2026 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

In a pure semiconductor, thermal excitation breaks 7 × 10¹² additional covalent bonds per cubic metre, with recombination neglected during the interval. How do carrier concentrations change?

A. Electrons increase by 7 × 10¹² m⁻³ and holes do not change
B. Holes increase by 7 × 10¹² m⁻³ and electrons do not change
C. The sum of electron and hole concentrations increases by 7 × 10¹² m⁻³
D. Both electrons and holes increase by 7 × 10¹² m⁻³

Example 2 · difficulty 2/5

What happens during electron-hole recombination in an intrinsic semiconductor?

A. A conduction electron fills a hole, reducing both carrier populations by one
B. Two conduction electrons combine to create one hole
C. A hole enters the conduction band and becomes a proton
D. A donor atom necessarily becomes ionised

Example 3 · difficulty 2/5

In the band picture, thermal generation of an intrinsic electron-hole pair corresponds to

A. an electron moving from the conduction band to the valence band
B. an electron crossing from the valence band to the conduction band
C. a proton crossing the forbidden gap
D. an ionised impurity moving between lattice sites

The evidence-first practice loop

1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
2. Attempt closed-bookExpose the concept or execution gap before rereading.
3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2026 Physics Semiconductor Electronics PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2026 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
