Question

Which is a dopant for a semiconductor that conducts electricity due to the movement of electrons?

thallium
indium
boron
antimony

Answer 1

Antimony is a dopant for a semiconductor that conducts electricity due to the movement of electrons. It is an n-type dopant, which means it adds extra electrons to the semiconductor material, increasing its conductivity. In contrast, boron and indium are p-type dopants that create holes (positive charge carriers), while thallium does not typically serve as a standard dopant in semiconductors.
