Q. Consider the following statements regarding the properties of Graphene:- The energy gap between the valence band and the conduction band is zero in Graphene.
- This characteristic of Graphene makes it highly suitable as a commercially viable transistor material.
Which of the above statements is / are correct?
Answer:
Only 1
Notes: Statement 1 is correct; Graphene is a zero-bandgap material, meaning the energy gap between the valence and conduction bands is essentially zero. However, statement 2 is incorrect as this property actually limits its use as a transistor, since effective switching typically requires a bandgap.
