PRINT NAME ___________________________________ INTRODUCTION TO MATERIAL SCIENCE MSE-150 QUIZ 5 I PLEDGE MY HONOR THAT I HAVE NEITHER GIVEN OR RECEIVED AID ON THIS EXAMINATION. I FURTHER PLEDGE THAT, IF I HAVE REASON TO SUSPECT THAT THE CODE HAS BEEN VIOLATED, I HAVE TAKEN OR WILL TAKE ACTION AS OUTLINED IN THE CODE. SIGNATURE ____________________________________ (1 point each) True or False A dielectric material between the plates of a capacitor increases the capacitance compared to that of the capacitor when there is a vacuum between the plates. True Fe 3 O 4 is a ceramic semiconductor which has a linear increase in its electrical conductivity as the temperature increases. False BaTiO 3 is a piezoelectric material where an electric field produces a mechanical response when it is in its cubic crystal structure. False The compound semiconductors are formed by elements from Columns II and VI or from Columns III and V of periodic table. True The compound semiconductor GaAs is an interesting electronic material since the electron mobility is considerably faster than in silicon.
