Saamaynta Weyn ee Electro-Optical ee Ge/SiGe Lammaanaha Quantum Wells

Sawir-qaadista Silicon-ku-saleysan ayaa hadda loo tixgaliyaa jiilka soo socda ee sawir-qaadista isgaarsiintaSi kastaba ha ahaatee, horumarinta modulators indhaha is haysta iyo kuwa hooseeya ayaa weli ah caqabad.Halkan waxaanu kaga warbixinaynaa saamaynta wayn ee korantada indhaha ee Ge/SiGeSaamayntan rajo-gelinta leh waxay ku salaysan tahay saamaynta quantum-ka aan caadiga ahayn ee Stark taasoo ay ugu wacan tahay xidhidhaynta kala duwan ee elektaroonnada iyo godadka ceelasha Quantum-ka ee Ge/SiGe.Dhacdadan waxaa loo isticmaali karaa si weyn loo hagaajiyo waxqabadka modulators iftiinka marka la barbardhigo hababka caadiga ah ee lagu sameeyay ilaa hadda silikoon photonics.Waxaan ku cabbirnay isbeddellada tusaha dib-u-celinta ilaa 2.3 × 10-3 ee korantada eexda ee 1.5 V oo leh hufnaanta habaynta u dhiganta VπLπ ee 0.046 Vcm.Mudaaharaadkani waxa uu u gogol xaarayaa horumarinta wax-bedeleyaasha heerka-xawaaraha sare leh ee wax ku oolka leh ee ku salaysan nidaamka agabka Ge/SiGe.
