The Role of Interfaces in Heterostructures

ChemPlusChem, 2017
AbstractNanocomposites represent an interesting class of materials because their applications are of multidisciplinary importance. Herein, interactions at the interface of heterostructures, leading to superior performance and sometimes to synergistic interactions, are highlighted.

Heterostructured Magnetic Nanotubes

Langmuir, 2006
Heterostructured 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, 2002
Semiconductor 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)

Designing heterostructured materials

Nature Materials
Heterostructures are composed of spatially distinct zones with differing mechanical and/or physical properties. When carefully engineered, these architectures can exhibit superior performance compared with their homogeneous counterparts. However, not all heterostructures inherently lead to a pronounced improvement in properties.

Magnetic Anisotropy of Heterostructures

2007
The chapter provides a detailed introduction to magnetic anisotropy of ferromagnetic ultrathin films and its analysis by ferromagnetic resonance on a tutorial level. While the microscopic origins of the magnetic anisotropy as well as recent developments in its theoretical description are shortly discussed, emphasis is put on a phenomenological ...

Heterostructure Injection Lasers

IEEE Transactions on Microwave Theory and Techniques, 1975
The 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 ...

Nanowire Heterostructures

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 ...

Introduction to Semiconductor Heterostructures

2012
We present an introduction to the physics of semiconductor nanostructures. We review the main assumptions of the \(k\cdot p\) method applied to a bulk crystal and then focus on the envelope function method to describe the electronic states of semiconductor heterostructures.
