With greater performance on account of the higher absorption of germanium in photodetectors as opposed to regular components such as silicon, additional and superior data is often acquired within the concentrate on wavelength.
Germanium can be an abundant aspect and it is rated since the 15th most considerable component during the earth’s crust. Germanium isn't current in its pure elemental variety and generally extracted from its zinc ore (sphalerite) and from ores of copper, silver and lead.
Allotropes Some factors exist in many unique structural types, named allotropes. Just about every allotrope has distinct Actual physical properties.
Germaniul nu prezinta un rol biologic in organism, desi actioneaza ca un stimulent metabolic. Sarurile de germaniu prezinta toxicitate scazuta pentru mamifere, insa au caracter letal pentru bacterii (fara a rezulta o aplicare practica a acestui comportament).
Until eventually Teal, not one person were in a position to provide silicon with a large enough purity to exchange germanium, but immediately after 1954 silicon started changing germanium in Digital transistors, and from the mid-sixties, germanium transistors had been pretty much non-existent.
In the twenties, investigate into the electrical Qualities of germanium resulted in the development of significant purity, one-crystal germanium. One-crystal germanium was employed as rectifying diodes in microwave radar receivers during Planet War II.
Main amongst these new products is germanium (Ge). This work opinions The 2 major remaining difficulties that get more info Ge based products need to overcome Should they be to exchange Si because the channel materials, namely, heterogeneous integration of Ge on Si substrates, and producing an appropriate gate stack. Upcoming, Ge is compared to compound III-V components with regards to p
Studiile pe animale indica faptul ca germaniul, in forma anorganica si organica, sunt absorbiti quick si aproape complet in tractul respirator si gastrointestinal. Distributia este relativ uniforma in cadrul organelor, insa exista o predispozitie pentru depozitarea acestuia in rinichi si ficat, fiind urmata de o excretie urinara rapida si acumulare pe termen lung in oase.
The most important problem to appreciate a Si-dependent interband laser is definitely the oblique bandgap of team IV elements, which leads to a very poor radiative recombination amount. Quite a few methods happen to be created to attain laser action from silicon.2–6 Using intersubband transitions in quantum cascade constructions signifies an thrilling alternative because such transitions are unbiased of the character of your bandgap.
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.

Utilizările curente ale germaniului includ încorporarea sa în sistemele de fibră optică și celule solare. Compușii germanici sunt de asemenea utilizați ca și catalizatori, precum și materiale pentru nanofire. Acest ingredient formează o gamă largă de compuși organometalici, precum tetraetilgermanul, de asemenea util în chimia organometalică.
Encyclopaedia Britannica's editors oversee subject matter places in which they have got substantial knowledge, regardless of whether from a long time of encounter received by engaged on that material or by using research for a complicated diploma. They write new information and verify and edit articles received from contributors.
