Fig. 5: One step growth of 1T′-MoTe2 and 2H-MoTe2 on a single substrate and SERS application of 1T′-MoTe2.
From: Selective phase growth and precise-layer control in MoTe2
In all, 532 nm Raman spectra from 1T′- and 2H-MoTe2 grown simultaneously on 300 nm SiO2/Si substrate (a); an optical image of the two MoTe2 phases grown simultaneously and separated by a ~20 μm strip of bare SiO2/Si substrate for a better optical contrast (b); 532 nm Raman spectra of 500 nM solution of Rhodamine 6G drop casted on different substrates (c); concentration dependent 532 nm Raman studies of Rhodamine 6G spectra drop cast on the surface of 5 L 1T′-MoTe2 film on SiO2/Si substrate (d).
