The band-gap shift of GaN:Mg epilayers on (0001)-oriented sapphire was studied as a function of uniaxial strain compression along the c-axis using time-resolved, optical absorption measurements in shock wave experiments. For longitudinal stresses ranging from 4 to 14 GPa, the band gap shift ...
The GaNAs/InGaAs short-period super-lattice(SPSL) with a feature of space separation in In and N constituent and equivalent 1 eV band-gap is one of important structures as an active region to achieve high efficiency of GaInNAs- based solar cell in the future. To experimentally realize the ...
In addition to the excellent electronic properties, the wide band gap of GaN means it also forms the basis of the incredibly successful violet laser diodes (LDs) and blue and green light emitting diodes (LEDs), achieved by alloying with indium, which are found at the heart of most modern ...

(10.2.8) to the experimentally determined pressure dependence of the band gap of GaNxAs1-x [25,27]. Figure 10.2 shows that this single fitting parameter provides a very good agreement with the experimental data reported by a number of research groups [28-31]. Sign in to download full-...
(1) can also be used to predict the melting behavior of GaN nanocrystals. Formula To deduce the size dependent band gap of GaN, a well-known Arrhenius expression for the size and temperature dependent electrical conductivity μ(D,T) is introduced, µ (D, T) = µ0 (D) exp ...
Examples of direct band gap semiconductor materials are gallium arsenide (GaAs), indium gallium arsenide (InGaAs), gallium nitride (GaN), aluminum nitride (AlN), cadmium sulfide (CdS), cadmium selenide (CdSe), cadmium tellurite (CdTe), zinc sulfide (ZnS), lead sulfide (PbS) and lead selenide...

We present an experimental investigation of band-gap shrinkage in n-type GaN using photoluminescence spectroscopy, as a function of electron concentration and temperature. The observed systematic shift of the band-to-band transition energy to lower energies with increasing electron concentration has been...
The optical properties ofGaNxP1xalloys(0.007x0.031)grown by gas-source molecular-beam epitaxy have been studied. An absorption edge appears inGaNxP1xat energy below the indirectΓV–XCtransition in GaP, and the absorption edge shifts to lower energy with increasing N concentration. Strong photomo...
