Liquid crystal electrography: Electric field mapping and detection of peak electric field strength in AlGaN/GaN high electron mobility transistors
The liquid crystal mixture E7, based on cyanobiphenyl, has been successfully employed to map electric field strength and distribution in AlGaN/GaN high electron mobility transistors. Using a transmitted light image through crossed polarizers the optical response of the liquid crystal deposited onto the surface of the devices was recorded as a function of source–drain bias, Vds. At a critical vo...
متن کاملLiquid Crystals in Electric Field
Phase transitions occur in various systems in electric field. To treat such problems we need to construct a Ginzburg-Landau free energy including electrostatic interactions and electric field effects under each given boundary condition.1) The gross variables include the order parameter ψ, the polarization p, and the charge density ρ. (Note ψ = p in ferroelectric systems.) In this letter we pres...
متن کاملElectron Mobility in InP at Low Electric Field Application
Temperature and doping dependencies of electron mobility in InP semiconductor has been calculated using an iterative technique. The following scattering mechanisms, i.e, impurity, polar optical phonon, acoustic phonon and piezoelectric are included in the calculation. It is found that the electron mobility decreases monotonically as the temperature increases from 100 K to 600 K. The low tempera...
متن کاملExtensional Flow of Nematic Liquid Crystal under Electric Field Gradient
Systematic asymptotic methods are used to formulate a model for the extensional flow of a thin sheet of nematic liquid crystal. With no external body forces applied, the model is found to be equivalent to the socalled Trouton model for Newtonian sheets (and fibers), albeit with a modified “Trouton ratio”. However, with a symmetry-breaking electric field gradient applied, behavior deviates from ...
متن کاملImplications of gate-edge electric field in AlGaN/GaN high electron mobility transistors during OFF-state degradation
Gate degradation in high electron mobility transistors (HEMTs) under OFF-state stress results from the high electric field near the gate edge. We investigate the evolution of this field over time in AlGaN/ GaN HEMTs upon OFF-state stress using a combination of electroluminescence (EL) microscopy and spectroscopy. EL analysis suggests that the electric field at the sites of generated surface def...
