Synthesis and Characterization of Ni-Doped ZnO Thin Films Prepared by Sol–Gel Spin-Coating Method

Bias and illumination-dependent room temperature negative differential conductance in Ni-doped ZnO/p-Si Schottky photodiodes for quantum optics applications

“…The Nickel-doped ZnO materials were synthesized as follows according to the outlines described by Ayachi et al, and Al-Ariki et al [12] , [26] . Firstly, 0.5 M of zinc acetate dihydrate was dissolved in 2-methoxyethanol for 1 hour at 60 ∘ C while stirring.…”

“…The electronegativity and ionic radius ( r ) of Ni ( r =0.69 Å) imply an affinity and good substitutional compatibility with Zn ( r =0.74 Å) with minimal distortion of the host structure [11] . Prior studies have shown that Ni doping maintains ZnO film transparency [12] while enhancing the electrical conductivity through two extra electrons. However, the trade-off is a reduction in the band gap e.g.…”

EFEK DAYA PLASMA TERHADAP SIFAT FOTOLUMINESEN FILM TIPIS ZnO DOPING Al

“…Berdasarkan perbedaan sifat dari bidang orientasi tersebut, maka dominasi bidang orientasi memberikan informasi terhadap aplikasi dari dominasi bidang orientasi Kristal yang dihasilkan. Misalkan dominasi bidang orientasi (002) dapat dimanfaatkan untuk bahan window layer pada teknologi sel surya (Ayachi et al, 2022;Salim et al, 2021), sementara untuk dominan bidang orientasi (103) merupakan kandidat bahan devais optoelektronik pada daerah UV (Challali et al, 2020). Namun demikian, penentuan pemanfaatan suatu bahan tentunya tidak hanya ditinjau dari struktur Kristal saja, tapi juga sifat-sifat yang seperti morfologi permukaan yang dapat diketahui melalui karakterisasi scanning electron microscope (SEM) dan atau atomic force microscope (AFM), komposisi penyusun Kristal yang diketahui melalui karakterisasi energy dispersive x-ray (EDX), EnergyDispersive X-ray Spectroscopy (EDS).…”
