IntisariTelah berhasil dilakukan penumbuhan lapisan tipis magnetite (Fe3O4) di atas substrat Indium Tin Oxide (ITO) dengan metode elektrodeposisi (ED), menggunakan Continue Direct Current (CDC). Karakterisasi XRD menunjukkan bahwa proses pemanasan sangat mempengaruhi terbentuknya lapisan tipis magnetite. Magnetite terdeposisi dengan struktur FCC dengan ukuran kristal 32,617 nm sampai 185,521 nm, dibawah kontrol konsentrasi surfaktan terhadap pelarutnya. Parameter deposisi optimum adalah ukuran kristal dan permukaan yang lebih halus. Parameter kisi masing-masing sampel adalah 8,313 , 8,365 , 8,354 , 8,351 , sedikit lebih rendah dari nilai standar 8.375 (JCPDS # 01-088-0315). Sedangkan jarak antar bidang kristal yang diperoleh berada pada kisaran 2,507 sampai dengan 2,522 . Hasil karakterisasi SEM menunjukkan bahwa magnetite tersebar merata di atas substrat ITO. Tiga sampel (K,O,P) terdeposisi dalam bentuk agregat dari kristal magnetite. Sedangkan sampel Q terdeposisi dalam bentuk lapisan. ABSTRACTMagnetite (Fe3O4) film was successfully deposited on a ITO substrat by Electrodeposition (ED) technique use a Continue Direct Current (CDC). XRD characterization show that the heating process is very influences the formation of a thin layer of magnetite. Magnetite deposited with FCC structure with crystal size of 32.617 nm to 185.521 nm, under the control of the surfactant concentration of the solvent. Deposition parameter optimum is refined crystal size and minimum surface roughness. Lattice parameter of each sample is 8. 313 , 8.365 , 8.354 , 8.351 , slightly lower than the standard value 8375 (JCPDS # 01-088-0315). While the spacing the crystal planes were obtained in the range of 2.507 to 2.522 . SEM characterization results showed that magnetite is spread evenly over the substrate Indium Tin Oxide (ITO). Three samples (A, C, D) deposited in the form of aggregates of magnetite crystals. While the Q sample deposited in the form of layer.KATA KUNCI: magnetite, electrodeposition, Continue Direct Current (CDC), ethylene glycol. I. PENDAHULUANLapisan tipis merupakan bahan dalam jangkauan beberapa nanometer atau nanolayer yang dibentuk oleh susunan dan penggabungan sifat-sifat atom. Lapisan tipis dibuat dengan teknik penumbuhan atom atau partikel pada permukaan substrat dengan ketebalan sampai orde mikrometer. Sifat umum lapisan tipis dari suatu bahan berbeda dengan bahan padatan, * E-MAIL: sylvina tebriani@yahoo.com hal ini disebabkan oleh perbedaan proses preparasinya, komposisi, morfologi dan strukturnya. Berbagai bahan yang memiliki potensi sebagai semikonduktor telah banyak diteliti, mulai dari bahan yang memiliki sifat fotokatalis, magnetic storage dan dielektrik. Lapisan tipis ferromagnetik oksida dapat digunakan sebagai bahan memori penyimpanan data yang terdiri atas bagian multilayer magnetik untuk menyimpan informasi [1].Sifat-sifat lapisan tipis yang ditumbuhkan dapat dimodifikasi sesuai dengan tujuan penerapannya. Kemampuan suatu bahan untuk diaplikasikan tidak terlepas dari inovasi terhadap unsur penyusun u...
Understanding science, especially physics, can not only be done with theory and formulation. It should relate the physics theory studied to everyday events. In addition, strengthening the characteristics of learning in madrasas can be done with an approach to religion (Qur'an science). The dichotomy occurring between science and religion makes them look like not interconnected. In fact, the Qur'an is the source of all sources of knowledge. The study of the integration between religion and physics presents a direction that can break the deadlock of physics problems. It is hoped to form an integration between religion and physics, which gives two understandings at once when learning. Examining the force and its relation to Newton's second law, also means examining the mass and acceleration. These quantities have a reciprocal relationship that can be peeled down in terms of religion and its relation to life. Mass can be analogous to the inertia (willingness) of a person to change his state, which is later also influenced by the quantity of the action (force) that a person will perform, and the determinant of the acceleration of his life (with a change in circumstances). Learning about force (F) will be closely related to acceleration and mass. A person with an enormous mass (m>>) will be more inert, because of which the acceleration he has will be smaller (a<<)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
