Low stress silicon (Si)-rich silicon nitride (SiNx) films are usually used as membranes of microcapsules for transmission electron microscopy (TEM). Their relatively high atomic number has a negative impact on resolution, which is a key factor that affects imaging performance. To improve resolution...
When used to expand, for example, Coulomb solutions, the required number of basis functions will depend on the largest radial distance up to which one needs to go. As such a distance grows the number of expansion coefficients increases too, simply because the never vanishing nature of a ...
It has been reported that ADF signal is proportional to the nth power of the atomic number Z, i.e., the Z contrast in textbooks and papers. Here we first demonstrate the deviation from the power-law model by quantitative experiments of a few 2D materials (graphene, MoS2 and WS2 ...
The interfacial structure of nitrous-oxide- (NO-)nitrided SiO[sub 2]/Si is determined on the basis of the configuration of the P[sub b] centers and the results of physical analysis. We used electron spin-resonance analysis to observe a decrease in the number of P[sub b] centers after ...
(rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas (specifically the isotope radon-...
(b) High-resolution ADF-STEM image of nanoparticles formed during the first stage (nucleation and monomer attachment). (c) Average particles size evolution (red) and the number of particles (blue) as a function of time. (d) High-resolution ADF-STEM image of a particle formed during the ...
The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer processors, such as the recently announced Apple A12 Bionic chip and Huawei Kirin 980, use 7 nm processes with 6.9 billion transistors on a centimeter square chip. The limits are being pushed to ...
Nitride coatings have been used in numerous applications to increase the hardness and improve the wear and corrosion resistance of structural materials, as... I Bertóti - 《Surface & Coatings Technology》 被引量: 283发表: 2002年 Results of apparent atomic oxygen reactions with spacecraft materials...
In recent years, low-dimensional transition metal chalcogenide (TMC) materials have garnered growing research attention due to their superior electronic, o
Atomic force microscope (AFM) is a powerful tool to investigate surface properties and structure of materials in nanometric scale. Flexibility, large number of potential signals, and its performance in various modes have been a great assistance for researchers to study different surfaces and different...
