Sentence examples for built-in polarization from inspiring English sources
These nitride devices are generally grown along the polar c-axis (Ga-polar), where the built-in polarization field decreases the overlap of the electron and hole wave functions and leads to quantum-confined Stark effect (QCSE) [1 4].
The electrostatic coupling is established through the built-in polarization due to the space charges and the intrinsic polarization variations between the ferroelectric layers.
The effect of built-in-polarization (BIP) field on thermal properties of InxGa1−xN/GaN heterostructure has been investigated.
Our result shows that the built-in-polarization field suppresses the scattering mechanisms and enhances the combined relaxation time.
Our study reports that room temperature thermal conductivity of AlxGa1−xN/GaN heterostructure is enhanced by built-in-polarization field.
The combined phonon relaxation time of acoustics phonons has been computed for with and without built-in-polarization field at room temperature for different aluminum (Al) content (x).
The built-in-polarization field at the interface of AlxGa1−xN/GaN heterostructure enhances elastic constant, phonon velocity, Debye temperature and their bowing constants of barrier material AlxGa1−xN.
However, the large lattice mismatch between GaN and AlN and their polarization properties induce a strong built-in electric field, causing a remarkable quantum-confined stark effect [QCSE] which reduces the internal quantum efficiency [IQE] of the QDs.
The built-in electric fields induced by spontaneous and piezoelectric polarizations at the hetero-interfaces, InGaN/GaN and AlGaN/GaN, are also included using the model described in Ref. [25], assuming 50% compensation of the polarization fields [26, 27].
This lens had a built-in rotating wheel mounted with three broadband (275 750 nm) neutral-density linearly polarizing filters (Polaroid HNP'B) with three different polarization axes (90°, 135° and 0° from the radius of the wheel).
Built-in electric field is absent in zinc-blend (ZB) GaN structures because the spontaneous polarization does not exist in the ZB GaN due to the higher crystal symmetry.
