What is the effect of the photoelectric effect on the conductivity of semiconductors? 

Best insight from top research papers

The photoelectric effect has an effect on the conductivity of semiconductors. In unipolar multivalley semiconductors, the diffusion of photoexcited nonequilibrium heavy and light electrons is a correlated process, similar to ambipolar diffusion in the case of an electron-hole plasma . The light-induced intervalley transitions in multivalley semiconductors result in an imbalance between the subsystems of light and heavy electrons, leading to the electromotive force (emf) through the Dember photovoltaic effect. The emf in a "metal-semiconductor-metal" structure is determined by the conductivity of the heavy and light electron subsystems, as well as the surface conductivity of the metal-semiconductor interface . Additionally, the photoconductivity of semiconductors, such as germanium, silicon, and certain intermetallic compounds, can be controlled to study other processes and has practical applications in these materials .

What are the factors that affect electrical conductivity in liquid?3 answersFactors that affect electrical conductivity in liquid include concentration, viscosity, and the presence of electrolytes. At low concentrations, the conductivity generally increases with concentration, but in some viscous solutions, the reduced ion mobility can cause a drop in conductivity. The conductivity of sugar solutions can be related to the modified Walden equation, while the conductivity of sodium carboxymethyl cellulose (NaCMC) solutions is not influenced by bulk viscosity. Instead, an ion "diffusion viscosity" can be calculated from the conductivity, which corresponds to the likely viscosity of the solution at a molecular scale. The electrical conductivity of water can be measured by inducing an alternating induced voltage on a second winding of a transformer, which changes with the electrical conductivity of water. A conductivity sensor with multiple electrodes can determine a large range of electric conductivity in a liquid medium. The presence of water clusters in dielectric liquids can affect the electrical conductivity, with the temperature dependence of conductivity decreasing gradually with increasing water content.
What are the factors that affect electrical conductivity in solutions?3 answersThe factors that affect electrical conductivity in solutions include the concentration of solutes, temperature, and the dielectric properties of the solvent. The concentration of solutes can either increase or decrease the electrical conductivity depending on the specific solute. For example, in the sodium hydroxide-ammonium hydroxide system, the electrical conductivity increases with increasing NaOH concentration but decreases with increasing NH4OH concentration. Temperature also plays a role, as the electrical conductivity of water and some polar solvents decreases with increasing temperature, while the limiting high frequency electrical conductivity passes through a maximum at a certain temperature range. Additionally, the dielectric properties of the solvent and the distance between ions in the solution can influence electrical conductivity.
