Abstract
SnSe₂ alloys have been investigated in recent times as potential n-type thermoelectric materials. In this study, the thermoelectric transport properties of a series of Sb-doped SnSe₂, Sn(Se_1-xSb_x)₂ (x = 0, 0.015, 0.03, 0.045, 0.06) alloys are investigated. The electrical conductivity was generally enhanced with Sb doping owing to a large..... More

Abstract
The addition of Cu to layered Bi₂Te₃-based thermoelectric alloys has been studied as an effective way to enhance thermoelectric transport properties. In this study, the influence of adding Cu to Bi₂Se₃ alloys, which have the same rhombohedral crystal structure as Bi₂Te₃, was investigated by synthesizing a series of Cu_xBi₂Se₃ (x..... More

Abstract
Chemical mechanical polishing (CMP) of bulk AlN was performed with colloidal silica slurry at pH 9 for different times. The result shows that colloidal silica slurry at pH 9, which has the relatively high surface charge of -50.7 mV is most stable, and it was selected as chemically optimum condition..... More
