中文摘要 我們發表利用脈衝雷射沉積法改變不同基板溫度(600-800°C)製備鋁摻雜氧化鎵(AGO)薄膜對於金屬-半導體-金屬光電偵測器(PDs)的影響。 AGO膜的結晶品質可透過提高基板溫度來改善。由於AGO(400)的出現,AGO(2 ̅01)的d-間距減小,而該平面的應變增加。上述現象可透過在膜中形成AGO(400)平面造成AGO(2 ̅01)平面產生壓縮應變來解釋。AGO PD在240 nm波長處顯示出最大吸收,並且增強的結晶品質將有益於元件性能。
英文摘要 We report on the effects of substrate temperature (600–800 °C) on metal–semiconductor–metal photodetectors (PDs) fabricated with aluminum doped gallium oxide (AGO) films by pulsed laser deposition. The crystal quality of the AGO films was improved by increasing the substrate temperature. Because of the AGO (400) appearance, the d-spacing of AGO(2 ̅01)decreased, whereas the strain of this plane increased. This could be explained by the formation of the AGO (400) plane in the films, generating a compressive strain in the AGO(2 ̅01) plane. The AGO PDs showed a maximum absorption at a wavelength of 240 nm, and the enhanced crystal quality would benefit the device performance.
