In this paper, we present our approaches to the development of fiber-coupled superconducting single photon detectors with enhanced photon absorption. For such devices we have measured detection efficiency in wavelength range from 500 to 2000 nm. The best fiber coupled devices exhibit detection efficiency of 44.5% at 1310 nm wavelength and 35.5% at 1550 nm ...

In situ XRD and NMR experiments combined with molecular dynamics simulations using the grand canonical ensemble (GCMD) show that cation size, charge and solvation energy play critical roles in determining the interlayer expansion of smectite clay minerals when exposed to dry supercritical CO2 under conditions relevant to the earth’s upper crust, petroleum reservoirs, and geological ...

We realized the excellent confinement of carriers in single-layer InAs quantum dots (QDs) via introducing two
AlGaAs confining layers (CLs), and then fabricated the corresponding rolled-up InGaAs/GaAs QD microtubes by
conventional photolithography and wet-etching. Subsequently, the as-fabricated AlGaAs confined QD microtubes
were transferred to a Si-based SiOx substrate using a simple liquid-assisted substrate-on-substrate transfer
process, thus obtaining the microtube ...

We apply first principles calculations to compare the carbon and boron nitride nanotube unzipping under atomic oxygen impact. We show that the attack of several oxygen atoms can cause bond breaking in nanotubes, but the structure of boron nitride nanotubes is less damaged than the structure of carbon ones. With increasing diameter, the structural damage ...

Formation of carbon nanoparticles is an important type of complex non-equilibrium processes that require precise atomistic theoretical understanding. In this work, we consider the process of ultrafast cooling of pure carbon gas that results in nucleation of an onion-like fullerene. The model is based on molecular dynamics simulation with the interaction between carbon atoms described ...

AlGaAs/GaAs microdisk lasers with InAs/InGaAs quantum dots region were transferred onto a silicon wafer using indium bonding. Microlasers have a joint electrical contact put over a residual n+ GaAs substrate, whereas their individual addressing is achieved by placing them p-contact down to separate contact pads. No effect of non-native substrate on electrical resistance, threshold current, ...

Существование однослойных нанотрубок, не нагруженных внутренним давлением, свидетельствует о необходимости учета моментного взаимодействия между атомами. В противном случае, слой атомов, формирующий нанотрубку, не имел бы изгибной жесткости, а стало быть, однослойная нанотрубка была бы неустойчива.
Ситуация здесь та же, что и в континуальной макромеханике. В основе таких популярных в инженерных расчетах континуальных моделей, как стержни и ...

Современные нанотехнологии давно нашли свое место в области лазерных и светоизлучающих структур, фотоэлектрических преобразователей, элементов оптоэлектроники и нанофотоники, а также в других областях науки и технологии. Одним из наиболее ярких примеров применения нанотехнологий является развития микропроцессорной техники, где за несколько последних десятилетий топологический размер затворов транзисторов уменьшился с единиц микрометров до единиц нанометров. Это привело ...
