Germaniul diferă de siliciu în privința disponibilității surselor de exploatare, în timp ce rezerva de siliciu este limitată doar de capacitatea de producție (din moment ce siliciul supply din nisip și cuarț).
Polycrystalline Ge slender films have captivated significant awareness as likely components for use in a variety of Digital and optical units. We not long ago developed a minimal-temperature good-section crystallization technological know-how for your doped Ge layer and realized the highest electron mobility inside of a polycrystalline Ge thin film. On this research, we investigated the consequences of strain over the crystalline and electrical Houses of n-type polycrystalline Ge levels. By inserting a GeOx interlayer specifically below Ge and deciding on substrates with various coefficients of thermal expansion, we modulated the strain while in the polycrystalline Ge layer, starting from about 0.
Figure 6b shows J-V qualities for three Al/2 nm ZnO/n−-Ge product with Ar plasma treatment. It is obvious which the J for different system is nearly exactly the same, indicating that the two ALD process and Ar plasma remedy have uniform effect on the development of recent density.
× MAP stands for "Least Marketed Price tag". The manufacturer of the item isn't going to enable us to publish our advertising selling price because it is below the worth they need to see their product advertised at.
In experiments, a derivative of germanium named spirogermanium has been shown to inhibit replication in sure cancer cells, but human reports present it's adverse results and isn't acceptable as an anticancer remedy, in accordance with the Memorial Sloan Kettering Cancer Center.
The location is protected. The https:// assures that you'll be connecting into the Formal Web-site Which any details you supply is encrypted and transmitted securely.
While it is of course happening, or to generally be more specific, By read more natural means fashioned - albeit briefly - during radioactive decay of other aspects, the level of francium in the world is tiny. It's been estimated that at any one time There exists a lot less than a kilogram with the ingredient in your entire earth's crust.
Of these, by far essentially the most correct prediction was for ekasilicon, occupying the slot we now give to germanium. Mendeleev came up with an atomic fat of 72, when compared to an true value of 72.
Identify your assortment: Identify need to be fewer than figures Opt for a collection: Struggling to load your assortment resulting from an error
Relative atomic mass The mass of an atom relative to that of carbon-twelve. This is certainly roughly the sum of the volume of protons and neutrons in the nucleus. In which more than one isotope exists, the value given will be the abundance weighted common.
Cu toate acestea, sărurile sintetice de germaniu sunt compuși nefrotoxici, iar compușii sintetici ai germaniului cu halogenii și hidrogenul devin toxine și au proprietăți iritante.
The oxide of germanium (GeO2) is usually referred to as germania. It really is widely Utilized in optical products and fiber optics. Additionally it is employed as a catalyst inside the manufacture of polyethylene terephthalate or PET plastic.
As a result of Mendeleev's prediction of ekasilicon, germanium's area to the periodic table was verified due to identical Attributes predicted and similar properties deduced from analyzing the mineral.
Encyclopaedia Britannica's editors oversee subject locations in which they may have comprehensive understanding, regardless of whether from many years of expertise attained by working on that material or by means of examine for a sophisticated diploma. They compose new content material and confirm and edit written content received from contributors.
