Heterostructured Magnetic Nanotubes
Langmuir, 2006Heterostructured magnetic tubes with submicrometer dimensions were assembled by the layer-by-layer deposition of polyelectrolytes and nanoparticles in the pores of track-etched polycarbonate membranes. Multilayers composed of poly(allylamine hydrochloride) and poly(styrene sulfonate) assembled at high pH (pH > 9.0) were first assembled into the pores ...

Terahertz semiconductor-heterostructure lasers
Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2002Semiconductor devices have become indispensable for generating electromagnetic radiation in everyday applications. Visible and infrared diode lasers are at the core of information technology, and at the other end of the spectrum, microwave and radio-frequency emitters enable wireless communications. But the terahertz region (1-10 THz; 1 THz = 10(12) Hz)

Heterostructure Injection Lasers
IEEE Transactions on Microwave Theory and Techniques, 1975The utilization of the nearly ideal heterojunction that can be achieved between GaAs and AL/sub x/ Ga/sub 1-x/As to confine both light and electrical carriers has lead to the evolution of several new classes as injection lasers with very low room-temperature current-density thresholds for lasing (/spl lsim/ 1000 A/cm/sup 2/), and structures whose ...

Annual Review of Materials Research, 2013
The nanoscale diameter and high aspect ratio of nanowires are the foundation of fascinating structure-property relationships derived from confinement, interface effects, and mechanical degrees of freedom. When heterostructures are formed by high-quality growth of dissimilar materials on or within nanowires, the interactions of the low-dimensional ...

Physics of Heterostructures and Heterostructure Devices
1988This topic belongs to the broader one of scale-dependent properties of inhomogeneous semiconductors. Most semiconductor devices depend on characteristic lengths, such as screening constant, carrier recombination length, inverse of pair creation rate, and their functioning is based on spatial inhomogeneities.

Quasiperiodic GaAs-AlAs Heterostructures
Physical Review Letters, 1985We report the first realization of a quasiperiodic (incommensurate) superlattice. The sample, grown by molecular-beam epitaxy, consists of alternating layers of GaAs and AlAs to form a Fibonacci sequence in which the ratio of incommensurate periods is equal to the golden mean $\ensuremath{\tau}$.

Epitaxial Nanosheet–Nanowire Heterostructures
Nano Letters, 2013We demonstrate synthesis of a new type of heterostructures that comprise two-dimensional (2D) nanosheets (NSs) epitaxially grown at one-dimensional (1D) nanowires (NWs). The synthesis involves materials with a graphite-like layered structure in which covalently bonded layers are held by weak van der Waals forces. GeS was used as a prototype material in
