چکیده

We used an improved cothermal evaporation route for the first time to achieve quaternary semiconductor nanostructured alloys, using an example of Zn(x)Cd(1-x)S(y)Se(1-y) nanobelts. The PL (bandgap) of these as-grown nanostructured alloys can be continuously tunable across the entire visible spectrum through experimentally controlling their compositions. Such widely controlled alloy nanostructures via composition/light emission provide a new material platform for applications in wavelength-tunable lasers, multicolor detectors, full-spectrum solar cells, LEDs, and color displays.

Strain-assisted bandgap modulation in Zn based II-VI semiconductors

The electronic structure of bulk ZnX (X1⁄4O, S, Se, and Te) under uniaxial strain along the [0001] direction or equibiaxial strain along the (0001) plane is investigated using hybrid density functional theory calculations and many-body perturbation theory. It is shown that compressive uniaxial (or tensile equibiaxial) strains lead to a structural phase transition in all the ZnX systems. This is...

Material parameters of quaternary III–V semiconductors for multilayer mirrors at 1.55 μm wavelength

Nine quaternary (Al,Ga,In)–(P,As,Sb) semiconductor compounds lattice matched to InP are investigated theoretically. Direct bandgap, refractive index at 1.55 μm wavelength, and thermal conductivity are calculated as a function of the composition. These material properties are important, e.g. in distributed Bragg reflectors of vertical-cavity lasers. The alloy systems AlGaAsSb, AlGaPSb and GaInPS...

A monolithic white laser.

Monolithic semiconductor lasers capable of emitting over the full visible-colour spectrum have a wide range of important applications, such as solid-state lighting, full-colour displays, visible colour communications and multi-colour fluorescence sensing. The ultimate form of such a light source would be a monolithic white laser. However, realizing such a device has been challenging because of ...

Hot Hole Enhanced Synergistic Catalytic Oxidation on Pt‐Cu Alloy Clusters

Hot holes in Pt-Cu alloy clusters can act as catalyst to accelerate the intrinsic aerobic oxidation reactions. It is described that under visible light irradiation the synergistic alcohol catalytic oxidation on Pt-Cu alloy clusters (≈1.1 nm)/TiO2 nanobelts could be significant promoted by interband-excitation-generated long-lifetime hot holes in the clusters.

Composition and bandgap-graded semiconductor alloy nanowires.

Semiconductor alloy nanowires with spatially graded compositions (and bandgaps) provide a new material platform for many new multifunctional optoelectronic devices, such as broadly tunable lasers, multispectral photodetectors, broad-band light emitting diodes (LEDs) and high-efficiency solar cells. In this review, we will summarize the recent progress on composition graded semiconductor alloy n...
