Route 3: Other

p004 / 3425 · Fabrication of the Cu3(HHTP)2-based SGMT

Metal precursors1 mM Cu(OAc)2 ethanolic solution

Linker precursors0.1 mM HHTP ethanolic solution

Solventsethanol; pure ethanol wash

AdditivesPiranha solution pretreatment, H2SO4 (95-98%)/H2O2 (30%) = 7:3; PDMS encapsulant; Ag/AgCl (sat. KCl) gate electrode

Atmospherehigh-purity N2 glovebox during annealing

Temperature85

Time0.5 anneal; each growth cycle used 20 min Cu(OAc)2 immersion and 40 min HHTP immersion

Substrate orientationOH-functionalised glass substrate with patterned Cr/Au source-drain electrodes; channel length L = 0.2 mm, width W = 6.0 mm

Work-upAfter each immersion step, substrates were carefully washed with pure ethanol; unwanted channel region removed and channel encapsulated with PDMS.

ActivationAnnealed at 85 C for 30 min in high-purity N2 glovebox.

Scalability contextCyclic layer-by-layer process; thickness controlled by growth cycle with ca. 10 nm per cycle.
