The polymer binder has a repeating unit represented by the formula(1), in which R1, R2, R3 and R4 are each a hydrogen, a halogen, a C1-20 substituted or non-substituted alkyl group or C1-20 substituted or non-substituted alkoxy group and R5 is a bond, a C1-20 substituted or non-...
Purpose of this chapter is providing the equilibrium expressions of the electron and hole concentrations in a semiconductor. For comparison, the cases of insulators and conductors are discussed qualitatively, and the concepts of conduction band, valence band, and generation of an electron-hole pair ar...
Charges generated in water are shielded by the polarization effect. The dielectric response which shields the charge is very fast in water47, and the electron-water collision considerably delays the recombination time between the electrons and the parent ion. For these reasons, many ionised electrons...
in stroboscopic mode. The pump laser’s polarization was controlled using a half-wave plate. During these experiments, the UTEM system was operated with a repetition rate of 200 kHz and less than one electron per pulse (single-electron mode) to avoid the space-charge effect. A post-column...
Drift Velocity Formula This formula is used to find thedrift velocity of electronsin a current-carrying conductor. When electrons with density n and charge Q causes a current ‘I’ to flow through a conductor of cross-sectional area A, Drift velocity v can be calculated through the formula I...
bonds. Understanding the nature of this bonding begins by knowing the number of electrons associated with each atom. With the information from a periodic table of the elements, and some straightforward arithmetic, you can calculate the number of electrons based on the chemical formula of a ...

In addition, the ion current included in the Poisson's equation has been treated as a tuning parameter. The analytical formula of the electron current density has been derived. The field-emissioncurrents in the presence of saturated ion currents can be enhanced to be nearly 1.8 times of the ...
Halide perovskites (HaPs) with formula AMX3generated enormous research interest because of their outstanding performance in optoelectronic devices, most notably in efficient solar cells1,2,3. These compounds are highly unusual among the established semiconductors because they feature an intriguing combination...
