Journal ArticleDOI
Antisolvent Crystallization Approach to Construction of CuI Superstructures with Defined Geometries
TL;DR: A facile high-yield production of cuprous iodide (CuI) superstructures is reported by antisolvent crystallization using acetonitrile/water as a solvent/antisolvent couple under ambient conditions.
Journal ArticleDOI
Quantum dot emitters in two-dimensional photonic crystals of macroporous silicon
Stefan Richter,Martin Steinhart,Herbert Hofmeister,Margit Zacharias,Ulrich Gösele,Nikolai Gaponik,Alexander Eychmüller,Andrey L. Rogach,Joachim H. Wendorff,Stefan L. Schweizer,Andreas von Rhein,Ralf B. Wehrspohn +11 more
TL;DR: In this article, the incorporation of semiconductor quantum dots as internal emitters into two-dimensional photonic crystals of macroporous silicon was reported, and a spectral modification of the emission by the surrounding photonic crystal was demonstrated for mercury telluride quantum dots when the emission coincides with the photonic band gap.
Journal ArticleDOI
Bringing order to the world of nanowire devices by phase shift lithography.
TL;DR: In this article, an upscalable process combining conventional micromachining with phase shift lithography will be demonstrated as a suitable tool for nanowire device technology.
Journal ArticleDOI
Atomic-layer-deposition alumina induced carbon on porous NixCo1 − xO nanonets for enhanced pseudocapacitive and Li-ion storage performance
TL;DR: A unique composite nanonet of metal oxide@carbon interconnected sheets is obtained by atomic layer deposition (ALD)-assisted fabrication and could provide a promising method to construct high-performance materials for energy and environment applications.
Journal ArticleDOI
Role of Carrier Gas Flow and Species Diffusion in Nanowire Growth from Thermal CVD
Andreas Menzel,Raya Goldberg,Guy Burshtein,Victor Lumelsky,Kittitat Subannajui,Margit Zacharias,Yeshayahu Lifshitz +6 more
TL;DR: In this article, the distribution of the growth species in a tube furnace was studied and the effect of diffusion and convection on the growth of nanowires was evaluated using simple considerations as well as more sophisticated numerical simulations.
