摘要

在30伏电压下，掺2%摩尔Mg的tio2 /ZnO表现出最高的选择性，选择性为1.54。计算了探测器的电导率，其中掺6%摩尔Mg的tio2 /ZnO在氢环境下的电导率最高，为18.54/ Ωm。掺杂4%摩尔Mg的tio2 /ZnO的响应时间为42 s。XRD结果表明，与未掺杂ZnO相比，掺杂Mg的ZnO具有更小的晶粒尺寸。

Karakterisasi Arus dan Tegangan Detektor Gas Hidrogen dari Bahan Semikonduktor Heterokontak TiO2/ZnO(Mg)

, TiO 2 /ZnO doped with 2% mole Mg showed the highest selectivity, which is 1.54 at a given voltage of 30 volt. Conductivity of detectors have been calculated, with of which TiO 2 /ZnO doped with 6% mole Mg showed the highest conductivity 18.54/ Ωm in hydrogen environment. Response time of TiO 2 /ZnO doped with 4% mole Mg is 42 s. XRD results showed that ZnO doped with Mg have lower crystal size compared with undoped ZnO.
