“…Atomic layer deposition (ALD) is used in binary oxide thin film technology due to excellent thickness control [43][44][45], low temperature processing [46,47], and effective deposition on nano-patterned substrates [48,49], due to the self-limiting process of precursor reaction. The separate introduction of each precursor inside the reactor assures that the ALD process is predominantly a surface reaction [45,50].…”

“…Hematite (α-Fe 2 O 3 ), an important member of the metal oxide family, is the most stable iron oxide with n-type semiconducting properties (Eg = 2.1 eV) . A wide range of applications have been demonstrated for α-Fe 2 O 3 nanostructured materials, such as field emitters, , magnetic materials, , photocatalysts, photoelectrochemical water splitting, lithium-ion batteries and dye-sensitized solar cells …”

“…In the last few years, considerable research efforts were devoted to improving the PEC performance of hematite photoanodes. A variety of strategies have been proposed and explored, such as nanostructuring for decoupling light absorption and charge carrier collection [6][7][8][9][10], doping with metals or non-metals to increase bulk conductivity [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], deposition of underlayers to improve charge collection [28][29][30], combination with gold nanoparticles or sensitization with semiconductor nanoparticles to enhance light harvesting [31][32][33][34], passivation with overlayers to reduce surface defects and trap states [34][35][36][37][38][39][40][41], creating heterojunctions to promote electron-hole separation [42][43][44], and coupling with catalysts to expedite the oxygen evolution reaction (OER) kinetics [45][46][47][48]…”
