Blue phosphorene (BlueP) is a graphene-like phosphorus nanosheet which was synthesized very recently for the first time [Nano Lett., 2016, 16, 4903-4908]. The combination of electronic properties of two different two-dimensional materials in an ultrathin van der Waals (vdW) vertical heterostructure has been proved to be an effective approach to the design of novel electronic and optoelectronic ...

To explore spintronics applications for Ge nanowire heterostructures formed by thermal annealing, it is critical to develop a ferromagnetic germanide with high Curie temperature and take advantage of the high-quality interface between Ge and the formed ferromagnetic germanide. In this work, we report, for the first time, the formation and characterization of Mn(5)Ge(3)/Ge/Mn(5)Ge(3) nanowire tr...

Abstract In this article an attempt has been made to determine the uni-directinal (001-direction) pressure effect on optical gain spectra and corresponding emission wavelength of a designed type-II nano-scale heterostructure based GaAsSb-InAs material system. As trial, range applied was kept as 1-3 GPa. On introducing uni-directional (in 1 GPa 3 GPa) QW heterostructure, is reduced significantly...

Realization of a robust nanotube-heterostructure tunneling transistors [Solid State Comm. 116, 569 (2000)] requires the difficult formation [Science 293, 76 (2001)] of a central nanoscale barrier separating a pair of outside metallic leads. Here I suggest an alternative surface-based assembly based on self-organization of one-dimensional metallic states on oxides and trapping well-resolved reso...

Electrical properties of epitaxial single-crystalline Si/SiGe axial heterostructure nanowires (NWs) on Si/111S substrate were measured by contacting individual NWs with a micro-manipulator inside an scanning electron microscope. The NWs were grown by incorporating compositionally graded Si1 xGex segments of a few nm thicknesses in the Si NWs by molecular beam epitaxy. The I–V characteristics of...

Multiple structures in one-dimensional photonic crystals have great potentials for ultrawide omnireflectors and tunable switches. In this paper, we study the propagation of electromagnetic waves in a one-dimensional heterostructure magnetic photonic crystal for both TE and TM incidence polarizations by means of the transfer matrix method. Results show that by stacking two magnetic photonic crys...

In this paper we introduce an approach to increase density of field-effect transistors framework a CMOS power amplifier. Framework the approach we consider manufacturing the inverter in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. After that dopant and radiation defects should by annealed framework o...

We design, fabricate, and test photonic crystal heterostructure cavity lasers in the InP material system. A heterostructure cavity is formed by interfacing two different photonic crystals such that a dispersion maximum of the inner lattice lies within the band gap of the surrounding lattice. Feedback to slow light modes of the central region results in a lower threshold and single mode operatio...

We demonstrate an efficient core-shell GaAs/AlGaAs nanowire photodetector operating at room temperature. The design of this nanoscale detector is based on a type-I heterostructure combined with a metal-semiconductor-metal (MSM) radial architecture, in which built-in electric fields at the semiconductor heterointerface and at the metal/semiconductor Schottky contact promote photogenerated charge...
