InGaAs/GaAs 3D architecture formation by strain-induced self-rolling with lithographically defined rectangular stripe arrays

“…2D electron gas transport properties on cylindrical surfaces in InGaAs/GaAs rolled-up tubes have been studied [6,11,12]. Structural, optical, and electrical characterizations have been performed [13][14][15][16][17][18]. Potential applications have been proposed and some preliminary results have been demonstrated, including as micro or nanoscale building blocks for MEMS and NEMS, for microinjections and ink-jet printing [19], magnetic conductors using ferromagnetic material filled coils [20], X-ray waveguiding [13], fluidics [21], and biology [22].…”

Effect of Mechanical Strain on the Optical Properties of Quantum Dots: Controlling Exciton Shape, Orientation, and Phase with a Mechanical Strain

“…An imposed nanomechanical strain [8][9][10][11] provides a route to dynamically reengineer QD structural symmetry to control excitations, polarize transitions, tune exchange splitting, induce entanglement, or modify coupling between QDs. These are capabilities needed to use QDs in nanophotonics, quantum information processing, and in optically active devices, such as optomechanical cavities [12,13] and semiconductor nanotubes [14][15][16][17].Nanomechanics is being studied for mass sensing [18,19], mechanical computing [20,21], and energy harvesting [22]. Structures are being cooled to approach the quantum limit for metrology and to provide coherent transducers that couple classical machines to quantum devices [23][24][25][26].…”

Combined Surface Plasmon and Classical Waveguiding through Metamaterial Fiber Design

“…This type of microtubular structure is producible via rolledup nanotechnology, 26,27 and classical waveguiding has been both observed in the near-infrared 28 and proposed for X-rays 30 using such structures. A 2D cross section is taken for this rolledup structure, and some of the modes which arise are shown in parts b and c of Figure 5.…”
