WitrynaImec reports here for the first time the MOCVD growth of WS2 on 300mm wafers, a key process step for device fabrication. The MOCVD synthesis approach results in thickness control with monolayer precision over the full 300mm wafer and potentially highest mobility matrial. The benefits of the MOCVD growth come at the price of a high … Witryna17 sie 2024 · The improved crystal quality of WS2 (and WSe2) domains was demonstrated by means of Raman spectroscopy, photoluminescence (PL) spectroscopy and HRTEM studies. Moreover, time-resolved PL studies show very long exciton lifetimes, comparable to those observed in mechanically exfoliated flakes. Thus, the …
