Nghiên cứu của FDA đưa ra kết luận rằng germani, khi sử đụng như là chất bổ sung dinh dưỡng, "thể Helloện một số nguy hiểm tiềm tàng cho sức khỏe con người".[6]
Acest ingredient nu are o funcție criticală pentru organisme, iar unii compuși organici ai germaniului au fost testați ca și posibile produse farmaceutice, însă fără nici un rezultat. Related cu siliciul și aluminiul, compușii germanici tind să fie insolubili în apă, având astfel un potențial scăzut de toxicitate orală.
36 Ohmic contacts were fashioned within the extremely doped semiconductor product working with deposited Ni metal annealed at 330 °C for thirty s to type NiGe.37 The linearity of your Get hold of resistances was evaluated with circular transmission line exam structures at ten K (begin to see the supplementary content). The GaAs/AlGaAs reference construction was processed into gratings with equivalent dimensions. It had been etched working with ICP with SiCl4/N2 chemistry and metalized with Ge/Au/Ni/Au serving as well as a selfaligned etch mask.
In experiments, a spinoff of germanium known as spirogermanium has become revealed to inhibit replication in particular most cancers cells, but human reports show it's adverse outcomes and isn't suitable as an anticancer procedure, based on the Memorial Sloan Kettering Most cancers Heart.

In summary, we proposed a novel technique of orbital split induced degree engineering as a result of sacrificial impurity coupling to attain productive n-type conduction in monolayer h-BN. To beat the doping asymmetry limitation of extremely-large bandgap h-BN, an especially shallow donor stage was built with the coupling of Ge 4 pz and O two pz orbitals. As a result of identical t2 symmetry and wavefunction character, these two orbitals can strongly few with each other. The introduction of O aspect-by-facet to Ge donor website can proficiently press up the donor stage by the formation of An additional sacrificial deep level. The in situ Ge-O doping in h-BN monolayer was effectively attained by employing GeO2 because the impurity precursor using a LPCVD process.
The steel-insulator-semiconductor (MIS) solution has proven it may possibly efficiently lessen the Get in touch with resistance to n-type Ge. These n-Ge lower resistance ohmic contacts are required to develop Ge NMOS units that may carry out on par with Ge PMOS products now set up.

Pure germanium reacts gradually with air at bigger temperature, all over 250°C and types germanium oxide. It doesn't react with dilute acids but is definitely dissolved in hot concentrated acids. Germanium reacts with halogens to sort compounds like germanium tetrachloride and germanium tetraiodide.

In thicker movies in which islanding takes place, a lot of defects thread in the direction of the surface wherever the islands at some point coalesce. Employing a surfactant to protect the second progress manner also alters the defect construction that sorts To alleviate the lattice pressure. LeGoues et al.
The immediate epitaxy approach is eye-catching due to its relative simplicity, and With all the assist of high temperature hydrogen annealing, this process has shown movies with small RMS surface roughness (below one nm) [38]. With regard to defect density however, direct epitaxy strategies have had combined effects [forty seven]. This technique frequently includes a two-action low temperature then large temperature (LT/HT) Ge expansion system. First a low temperature, minimal progress amount “seed” layer is developed which is meant to confine the vast majority of defects. Along with Ge’s lower floor diffusivity, reducing the growth temperature tends to prevent the impinging Ge from forming islands around the surface, resulting in flatter and even more homogenous coverage in the Si substrate.
