Salt‐Assisted Low‐Temperature Growth of 2D Bi2O2Se with Controlled Thickness for Electronics

“…[26][27][28][29][30][31] In order to achieve Bi 2 O 2 Se-based FETs, the acquisition of large-sized atomically thin 2D material is of considerable significance. So far, 2D Bi 2 O 2 Se has been synthesized by various techniques, including molecular beam epitaxy (MBE), [32] pulsed laser deposition (PLD), [33] wet-chemical methods, [34][35][36][37] physical vapor deposition (PVD), [30] and CVD method. [25,28,[38][39][40][41][42][43] Among these growth strategies, Bi 2 O 2 Se attained by PLD or MBE requires expensive equipment and ultra-high vacuum.…”

Hydrothermal-Dependent Synthesis of Exfoliated Nickel Cobaltite Layers for Simultaneous Determination of IARC Group 2B, 3B Carcinogens

“…The regulated rate of OH – ions controls the crystal growth. The material produced was a nanosheet structure with the aid of ethylene glycol . Calcination of 3 h of Ni–CoOOH at 400 °C in N 2 atm.…”

Defect-induced photogating effect and its modulation in ultrathin free-standing Bi2O2Se nanosheets with a visible-to-near-infrared photoresponse

“…Different synthesis techniques have been adopted to obtain the high crystal quality and scalable production of 2D Bi 2 O 2 Se. 14,[17][18][19][20][21] Based on its applications, researchers have adopted various synthesis/growth routes, such as chemical vapor deposition (CVD)-grown millimeter-sized single crystals of Bi 2 O 2 Se for phototransistors, 17 the catalyst-free CVD-growth of Bi 2 O 2 Se nanoribbons for phototransistors, 22 the solution-based top-down synthesis of Bi 2 O 2 Se quantum dots for cancer photothermal therapy, 23 etc. However, further investigations are necessary to bridge the gap between synthesis and applications in an orderly manner by unraveling the hidden properties of Bi 2 O 2 Se nanostructures.…”
