Engineering the Morphology and Component via Multistep Deposition of CsPbBr3Films toward High Detectivity and Stable Self‐Powered Photodetectors

“…[3][4][5] Compared with organic-inorganic lead halide perovskites, cesium-based all-inorganic perovskites show highly enhanced stability to moisture, oxygen, heat and better photo-stability. [6][7][8][9][10][11] In the past few years, cesium lead bromide (CsPbBr 3 ) with the various morphologies such as Self-powered perovskite photodetectors (PDs) have attracted tremendous interest for their promising advantages such as fast response speed and high detectivity. However, they usually suffer from severe operating instability issues stemming from the poor film quality, impurity phase formation, and numerous surface defects.…”

Vorticity-induced flow-focusing leads to bubble entrainment in an inkjet printhead: synchrotron X-ray and volume-of-fluid visualizations

“…Drop-on-demand inkjet printing is an accurate, non-contact, and highly reproducibly droplet deposition method that can be used to print liquids with a wide range of physical properties [1][2][3][4]. Today's applications of inkjet printing reach far beyond printing graphics on paper as inkjet technology is now used for the fabrication of electroluminescent displays [5,6], electronic circuits [7][8][9], and biomaterials [10][11][12].…”

Meniscus dynamics and selective evaporation in inkjet printing

“…The high control over the ink droplets has led to the use of inkjet printing in applications beyond the printing of graphics. Using light-emitting polymers, and their self-assembling properties during the drying process, the high control in depositing the droplets using inkjet printing has been used to develop organic electroluminescent displays [6,7]. The use of solutions containing conductive polymers as ink has also led to the printing of electronic circuits [8], which was developed further into using inks containing graphene [9,10].…”

“…Drop-on-demand (DoD) inkjet printing is well-known for its highly-controlled and non-contact deposition of picoliter droplets [1][2][3][4]. The high degree of reproducibility associated with inkjet printing, along with the ability to print across a wide range of liquid properties, has opened inkjet printing to a wide use in a multitude of application areas beyond graphics printing, including the fabrication of electronic displays [6,7], electronics printing [8][9][10], and in life sciences [11][12][13]. Typically, the inks used in inkjet printing are multicomponent, consisting not only of colored pigments and surfactants, but also of a collection of cosolvents with varying volatilities.…”
