dr. eriksson is working on a material called selenium. she is adding a certain number and type of atoms to the selenium, which will control its conductivity. selenium is most likely what kind of material? semiconductor conductor superconductor insulator
Answer
Brief Explanations:
Selenium has properties that allow its conductivity to be controlled by adding specific atoms. This is characteristic of semiconductors. Conductors have high conductivity without such control - altering doping, superconductors have zero - resistance under certain conditions which isn't mentioned here, and insulators have very low conductivity that isn't easily controlled in this way.
Answer:
semiconductor
