In this article, we have considered the p-i-n Ge photodetector with ZnSe passivating layer. Passivation layer needs to be protected from dust, rain drops and other external influences. However, passivation can cause errors in image. When creating a on Ge, which is used photodetectors, found two additional phases GeSe GeSe2 that do not contradict their state diagram. The above an essential effec...

We introduce a low temperature process for coating InGaN/GaN light-emitting diodes (LEDs) with h-BN as passivation layer. The effect of on device performance and reliability is investigated. At −5 V, the leakage current passivated LED was −1.15 × 10−9 A, which one order lower than reference LED’s −1.09 10−8 A. layer minimizes characteristics operating by acting heat dispersion With reduced work...

Although lithium–sulfur batteries exhibit a high initial capacity, production costs and lack of cyclability are major limitations. Here we report a liquid-based, low-cost and reliable synthesis method of a lithium–sulfur composite cathode with improved cyclability. An open network of Conductive Carbon Black nanoparticles (Cnet) is infused with a sulfur network (Snet) to form sponge-like network...

2014 It is shown that layers of polysilicon doped with oxygen (polydox) can be used for the passivation of underlying p-n junctions. The conduction mechanism was derived from measurements in layers directly deposited on to silicon crystals. At room temperature we found PooleFrenkel conduction changing at higher temperatures, presumably, to hopping in localized states. REVUE DE PHYSIQUE APPLIQUÉ...

The corrosion behaviour of three new non-toxic titanium alloys for use as biomaterials has been investigated. The corrosion current densities of these Ti alloys have low values, indicating a passive state that is stable with time. These values were calculated by using both direct and alternate current methods. The comparison with Ti–6Al–4V, widely used as biomaterial, shows slightly lower corro...

Magnetic patterning, with designed spatial profile of the desired magnetic properties, has been a rising challenge for developing magnetic devices at nanoscale. Most existing methods rely on locally modifying magnetic anisotropy energy or saturation magnetization, and thus post stringent constraints on the adaptability in diverse applications. We propose an alternative route for magnetic patter...

In this work, aluminum oxide films with excellent passivation effects were prepared on the rear-side surface of passivated emitter and rear cells (PERCs) using a self-developed spatial atomic layer deposition system. Various rear-side surface morphologies were obtained through different etching treatments. We compared the PERCs with standard etching treatment and further polishing processes on ...

Ultrathin black phosphorus is a two-dimensional semiconductor with a sizeable band gap. Its excellent electronic properties make it attractive for applications in transistor, logic and optoelectronic devices. However, it is also the first widely investigated two-dimensional material to undergo degradation upon exposure to ambient air. Therefore a passivation method is required to study the intr...
