“…Moreover, single significant (100) diffraction peak, with height intensity, was observed for the ZnO film which indicate that the ZnO film have preferential a-axis orientation perpendicular to the crystallographic plans (100). These results can be explained as it was expressed in the literatures [20,23,24,27].…”

“…3, it is worth to bear in mind that the Urbach tail energy is closely related to the disorder in the film network. One can see that a minimum Urbach energy was reached at 350°C, which means the adequate temperature for less disorder, which may be attributed to the similar ionic radius between O 2-and Zn 2+ , as it was expressed in the literatures [23][24][25][26]. The I-V characteristic of ZnO thin film is shown in Fig.…”

Abstract. The transparent conducting ZnO thin films were deposited on glass substrate by ultrasonic spray technique. The optical, electrical and structural properties of the ZnO thin films were studied as a function of the substrate temperatures in the range of 300 to 400 °C. The as deposited film exhibit a hexagonal structure wurtzite and (101) oriented.The value of grain size G = 28 nm is measured of ZnO film at 350 °C. All the films having high transparency in the visible region, the band gap energy decreased from 3.44 to 3.29 eV with increasing the substrate temperatures from 300 to 400 °C, respectively according to the Burstein-Moss effect (blue shift of Eg). The Urbach energy decreased reaching to minimum at 350 °C; indicating to decrease of the defects. The electrical resistivity of the films at 350 °C is 50 Ω.cm. A systematic study on the influence of the substrate temperatures on the optical, electrical and structural properties of ZnO thin films deposited by ultrasonic spray has been reported.

“…The film doped at 2 wt% has higher and sharper diffraction peak indicating an improvement in (0 0 2) peak intensity compared to the undoped ZnO thin film and the films doped at 1 and 3 wt%. The deposited films exhibit nanocrystalline structure with hexagonal wurtzite structure from the spectra [16,17]. This indicates that all films have preferential c-axis orientation along the (0 0 2) plane [18].…”

“…Film tipis ZnO maupun ZnO doping telah dideposisikan dengan berbagai macam teknik, seperti sputtering [5][6][7] , MBE (molecular beam epitaxy) [8] , CVD (chemical vapor deposition) [9] , MOCVD (metal organic chemical vapor deposition) [4] , electrochemical deposition [10] , pulsed laser deposition [11] , sol-gel [12][13] dan spray [12,[14][15][16][17][18] . Dibandingkan dengan teknik lain, spray merupakan teknik yang sederhana, tidakvakum dan murah [17] .…”

“…Salah satu paramater yang telah dipelajari pada fabrikasi film tipis dengan metode spray adalah perlakuan panas, seperti suhu perlakuan panas, waktu perlakuan panas dan lingkungan perlakuan panas. Peningkatan suhu perlakuan panas dalam lingkungan udara menunjukkan peningkatan pada struktur film tipis ZnO yang berakibat pada peningkatan sifat optiknya [12] . Studi lain oleh Gencyilmaz et al [16] menunjukkan bahwa waktu pada perlakuan panas mempunyai efek yang signifikan terhadap surface morfologi, sifat optik dan sifat listrik dari film tipis ZnO.…”

IntisariKarakterisasi XRD telah digunakan untuk mempelajari efek perlakuan panas tunggal dan ganda pada fabrikasi film tipis ZnO doping Al (AZO) nanokristal yang dideposisikan dengan teknik spray. Pada perlakuan panas tunggal, film tipis AZO nanokristal dengan struktur polikristal heksagonal wurtzite terbentuk pada suhu 500 °C dan 600 °C. Peningkatan suhu menyebabkan peningkatan ukuran kristal dan pengurangan kerapatan dislokasi. Perlakuan panas ganda pada film tipis AZO nanokristal mengakibatkan perubahan kecil pola difraksi. Hal ini mengindikasikan bahwa parameter kristal film tipis AZO nanokristal berubah setelah mendapat perlakuan panas kedua. Film tipis AZO nanokristal yang diberikan perlakuan panas pada suhu 500 °C dalam lingkungan udara dan dilanjutkan hingga suhu 600 °C dalam kondisi vakum memperlihatkan bahwa rata-rata ukuran kristal berkurang dan muncul cacat kristal (regangan dan kerapatan dislokasi meningkat). Hasil yang berbeda ditunjukkan pada film tipis AZO nanokristal yang diberikan perlakuan panas pada suhu 600 °C dalam lingkungan udara kemudian dilanjutkan dengan suasana vakum. Kualitas kristal film tipis AZO nanokristal meningkat, yang diindikasikan dengan peningkatan ratarata ukuran kristal, berkurangnya nilai regangan dan kerapatan dislokasi. Berdasarkan pada hasil yang didapat, perlakuan panas ganda berpengaruh pada parameter dan kualitas kristal film tipis AZO nanokristal yang dideposisikan dengan teknik spray.
