Germaniul diferă de siliciu în privința disponibilității surselor de exploatare, în timp ce rezerva de siliciu este limitată doar de capacitatea de producție (din second ce siliciul present din nisip și cuarț).
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]
The overall technique for SME is as follows. The Si substrate is to start with capped with ~one ML of your surfactant. The initial surfactant investigated for Ge/Si advancement was As. The extra valence electron from your As while in the capping layer fills the dangling bonds in the Si floor, resulting in a steady, or energetically favorable termination. Next capping layer deposition, Ge growth starts. Surface termination with As stays energetically favorable Because the Ge surface also contains dangling bonds.

)2O3 and subsequently heated to 450 °C underneath an Sb flux to induce an amorphous to crystalline transformation with the Ge. The Sb flux was located to scale back surface area roughening in the course of recrystallization. The caliber of the Ge surface area, when it comes to RMS roughness and TDD, wasn't described.

Ge gate stacks have manufactured remarkable strides because of many years of Global collaborative effort. Two passivation strategies have emerged from in excess of a decade of study. GeO
The place of wherever germanium need to be put on the periodic table was under discussion through the time as a result of its similarities to arsenic and antimony.
XW assisted to revise manuscript. HL aided to execute the measurements. HHZ and XC helped to deposit ZnO. YH offered constructive assistance within the drafting. Every one of the authors browse and authorized the final manuscript.
The above dialogue has triggered a alternative of two paths, the twin-Ge route (for both of those NMOS and PMOS) or maybe the check here III-V/Ge path (NMOS/PMOS). To be sure, There's also a chance of a dual-III-V route; or it could be found the efficiency benefit of Ge and III-V over strained silicon (which happens to be itself a going concentrate on) fails to justify the rise in complexity and value. The former seems the the very least probable of all solutions, plus the latter falls exterior the scope from the existing short article. This critique 1st summarizes the two main problems that should be get over to achieve either path involving Ge: heterogeneous integration of Ge on Si, and developing a suitable gate stack.
Germanium minerals may also be current in zinc ores, and industrial production of germanium is carried out by processing zinc smelter flue dust.
