From shaping to functionalization of micro-droplets and particles

“…[1][2][3][4][5][6] Since microdroplets possess a wide range of structural and functional abilities, they are important for numerous applications in elds such as biomedical, food, pharmaceutical, environmental, robotics, and energy. [7][8][9][10][11][12][13] Emulsions are thermodynamically stable dispersions of liquid mixtures consisting of at least two immiscible liquids, such as oil and water. 14,15 The emulsions are designated as A/B emulsions, indicating that phase A is covered by phase B (i.e.…”

Dipolar Alignment in a Ferroelectric Dielectric Layer of FeFETs to Boost Charge Mobility and Nonvolatile Memory

“…The alignment of C–F dipoles in the ferroelectric layer near the semiconductor–dielectric interface of the FeFET plays a pivotal role in boosting the charge transport through the semiconductor layer. Importantly, for a stable and durable device performance, we deposited copper phthalocyanine (CuPc) as the active semiconductor layer in the FeFET under ultrahigh vacuum (UHV) owing to its outstanding thermal and photochemical stability. − Previously, CuPc-embedded device configurations have shown potential in the development of chemical sensors, organic light emitting diodes (OLEDs), photovoltaic cells, and nonlinear optics with enhanced performances. − In the present scenario also, the use of CuPc as the active semiconductor with the fast-quenched ferroelectric polymer as the dielectric in the FeFET device ensures ∼35% increase in the charge carrier mobility and enhances the nonvolatile property.…”
