WebMost InGaAs devices are grown on indium phosphide (InP) substrates. In order to match the lattice constant of InP and avoid mechanical strain, In 0.53Ga 0.47As is used. This composition has an optical absorption edge at 0.75 eV, corresponding to a cut-off wavelength of λ=1.68 μm at 295 K. WebFeb 1, 2016 · High-frequency dielectric constant in nanosized InAs versus quantum dot radius using different models. This suggests that the capacity of storing electromagnetic energy for InAs quantum dots is weaker than that of bulk InAs and hence the InAs quantum dots become good insulators.

WebThe dielectric constant formula is: Where: C = capacitance using the material as the dielectric capacitor. C 0 = capacitance using vacuum as the dielectric. ε 0 = Permittivity of free space (8.85 x 10 -12 F/m i.e. Farad per metre) A = Area of the plate/sample cross section area. T = Thickness of the sample.
