Transition metal ferrites, such as CoFe2O4 (CFO) and NiFe2O4 (NFO), have gained increasing attention as potential materials for supercapacitors. Since chemical vapor deposition (CVD) offers advantages like interface quality to the underlying substrates and the possibility for coverage of 3D substrates, two CVD processes are reported for CFO and NFO. Growth rates amount to 150 to 200 nm h−1 and yield uniform, dense, and phase pure spinel ferrite films according to X‐ray diffraction (XRD), Raman spectroscopy, Rutherford backscattering spectrometry and nuclear reaction analysis (RBS/NRA) and scanning electron microscopy (SEM). Atom probe tomography (APT) and synchrotron X‐ray photoelectron spectroscopy (XPS) give insights into the vertical homogeneity and oxidation states in the CFO films. Cation disorder of CFO is analyzed for the first time from synchrotron‐based XPS. NFO is analyzed via lab‐based XPS. Depositions on conducting Ni and Ti substrates result in electrodes with pseudocapacitive behavior, as evidenced by cyclovoltammetry (CV) experiments. The interfacial capacitances of the electrodes are up to 185 µF cm−2.

“…Herein, we summarize the traditional and innovative synthesis approaches of typical spinel ferrite-based thin films, including solid phase methods, solution phase methods, and vapor phase methods. The solid phase approaches consist of combustion, pulsed laser and decomposition methods, and so on (Suzuki, 2001;Hao et al, 2018a;Nikam et al, 2020). The solution phase approaches contain chemical solution deposition, sol-gel, solvothermal, and electro-chemical methods, etc.…”

“…Electrical performance and application of spinel ferrite-based thin films, especially in emerging random access memories and energy storage devices, have recently achieved great attention owing to the shortcomings of Flash memories and increasing fossil energy consumption. The spinel ferrite-based thin films have also been applied in many storage fields, such as resistive random access memory, supercapacitors, Li-ion batteries, electrocatalysts, and so on (Hu et al, 2012a;Wang et al, 2013;Hu et al, 2014;Hwang et al, 2017;Sagu et al, 2017;Jiang et al, 2018;Nikam et al, 2020;Dongale et al, 2021). Spinel ferritebased resistive switching materials are one of a few promising resistive random access memory candidates.…”

Tan-Ong Pek Loon and Ms. Tan-Ho Ser Luan, for their untiring technical support throughout my research project.I would like to thank my friends, especially Catherine Cai and Nicholas Foo, and family, Mum, Dad, Sis, Guojie, my niece and nephew and my in-laws, many of whom are also the same people acknowledged above. They are the ones who have always provided a welcoming environment to return to and to rest, and who were always supportive of my ambitions. They are the bedrock on which my experiences are built upon. My parents, sister and her family are an especially large part of this equation, always being there when I need the support.My best friend, Sheena Lee deserves a mention and much appreciation all on her own, for her company, working endless late nights with me. She was and is always there to lend an encouraging smile, or a deep hug, to keep me going, and her infectious enthusiasm is always welcome through particularly tough times.To my wife and partner-in-crime, Yvonne Yap. She is to blame for leading me on this path of research, for inspiring in me my thirst for knowledge through every single day I'm with her. Despite all of the challenges we have faced, accommodating each other's needs and being there for each other, Yvonne has always found the time and space to be kind, gracious and understanding. She is the reason I am who I am today, and I will be forever grateful to her for that. And as much as she supports me, her own intense quest for knowledge constantly amazes and inspires me to do more. Yvonne is at once both an inspiration in my research, as much as the safe harbour I return to.Last, but certainly not least, to those who I have not specifically mentioned here: thank you, in all the ways you have helped me in this journey. You are not forgotten.
