Presentation Transcript
What is the formula for the Seebeck coefficient? (Remember: V is the change in voltage and T is the change in temperature).
• S = -V/T
• S = - T/V
• S = V/T
• S = T/V
What material is studied in Dr. Constantin’s group?
• Manganese Oxide
• Magnesium Oxide
• Magnesium Nitride
• Manganese Nitride
What is the difference between a metal and a semiconductor (both at the room temperature)?
• Only metal conduct electricity
• Only semiconductors conduct electricity
• Both conduct electricity
