在算歷屆試題時有兩提不會算 請材料高手幫幫忙 1.If zinc oxide is heated a low oxygen pressure,it will become conductive. Assume the defect structure is of the Frenkel type, with zinc ions occupying the interstitial position. How do the concentrations of electrons change with the oxygen pressure if the interstitial zinc ions are (A)doubly charged and (B)singly charged? 2.For aluminum, the heat capacity at constant volume Cv at 30K is 0.81 J/mole-K,and the Debye temperature is 375 K,Estimate the specificheat at 55K and 430K 清大家幫忙解一下 謝謝大家 --
