Orthogonally polarized semi-polar (202¯1) InGaN/GaN-based MCLED array
None:
Orthogonally polarized light technology holds significant promise for applications in visible light communication, 3D displays, and medical imaging. This study introduces a novel semi-polar (202¯1) InGaN/GaN-based microcavity light-emitting diode (MCLED) capable of simultaneously generating orthogonally polarized light parallel and perpendicular to the [101¯4¯] axis. An optical resonant cavity was formed by employing SiO2/TiO2 distributed Bragg reflectors (DBR) and Ag as reflectors, enhancing thermal dissipation and achieving a high polarization ratio (∼0.89). A parallel MCLED array was fabricated, significantly improving output power while maintaining orthogonal polarization. This work advances orthogonally polarized light technology, offering new possibilities for practical applications.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
