Ingaas coefficient of thermal expansion

WebbWhen using Tangent coefficient of thermal expansion, the integrate operator is used. It is called with the two integration limits being the reference temperature < phys>.Tref and the current temperature < phys>.T, where < phys> is the tag of the physics interface. If you define the expression for the coefficient of thermal expansion yourself, you must … The measured coefficient of thermal expansion is 5.66 × 10 −6 K −1. This is significantly larger than the coefficient for InP which is 4.56 × 10 −6 K −1 . A film that is exactly lattice-matched to InP at room temperature is typically grown at 650 °C with a lattice mismatch of + 6.5 × 10 −4 . Visa mer Indium gallium arsenide (InGaAs) (alternatively gallium indium arsenide, GaInAs) is a ternary alloy (chemical compound) of indium arsenide (InAs) and gallium arsenide (GaAs). Indium and gallium are ( Visa mer Indium gallium arsenide (InGaAs) and gallium-indium arsenide (GaInAs) are used interchangeably.
