28/1/2009· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) []. One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.
In this contribution, boron-doped diamond (BDD) is used as an environmental friendly alternative electrode to ASV analysis of uranyl ions. Under optimal conditions, a wide linear relationship over the concentration range from 1 ppb to 10 ppm can be obtained and a very low detection limit of about 0.012 ppb has been calculated by the standard 3 method.

8/12/2020· Boron-doped silicon carbide (SiC:B) was fabried. • SiC:B was mainly composed of the 3C–SiC phase. • Silicon or carbon atoms were replaced with boron atoms. • The SiC:B electrode showed high reactivity and durability. • Sensitivity of the SiC:B electrode was
This paper presents the appliion of a multiscale field theory in modeling and simulation of boron-doped nanocrystalline silicon carbide (B-SiC). The multiscale field theory was briefly introduced. Based on the field theory, numerical simulations show that intergranular glassy amorphous films (IGFs) and nano-sized pores exist in triple junctions of the grains for nanocrystalline B-SiC.

1/10/2019· We created a diffusion couple using boron carbide (with millimeter grain sizes) and silicon hexaboride (SiB 6) to achieve a Si concentration gradient within one boron carbide grain. We then used nanoindentation to induce amorphization and applied advanced microscopy techniques to uncover the microstructure of the quasi-plastic zones from both the undoped and Si-doped regions.

In many appliions, for cost-efficient operation, the use of oxide and non-oxide ceramic components such as doped Zirconia (ZrO 2), Al 2 O 3-ZrO 2 mixed ceramics, Silicon Carbide (SiC) or Si 3 N 4 is often the ultima ratio.
In the present work, we investigated donor-acceptor-pair emission in N-B doped fluorescent 6H-SiC, by means of photoluminescence, Raman spectroscopy, and angle-resolved photoluminescence. The photoluminescence results were interpreted by using a band diagram with Fermi-Dirac statistics. It is shown that with N and B concentrations in a range of 1018cm−3 the samples exhibit the most intense
