Fig. 1: 2D Ga2O3 film’s preparation process and morphologies.
From: Printing ultrathin Quasi-2D Ga2O3 for fast yet highly responsive vertical photodetectors
a Schematic description of 2D Ga2O3 thin-film preparation from liquid GaInSn through liquid metal nanoprinting process. An optical image of large-area Ga2O3 layer on the 2 in. SiO2 substrate is shown on the bottom right. b Optical image of the printed Ga2O3 on 300 nm SiO2/Si. c AFM image of Ga2O3 film, where the inset was the height profile. d Thickness distribution of the printed 2D Ga2O3 at different locations.
