Materials Characterization
We do all of our standard characterization on campus using the excellent facilities of VISTEC's Frontier Research Center (FRC). Common techniques that we use at FRC include (see the full list at https://www.vistec.ac.th/research/research-services)
Absorption spectroscopy
Photoluminescence spectroscopy (Steady-state, time-resolved, and temperature-dependent)
Fourier-transform infrared (FTIR) spectroscopy
Raman spectroscopy
Scanning electron microscopy (SEM)
Transmission electron microscopy (TEM)
Nuclear magnetic resonance (NMR) spectroscopy
Mass spectrometry (MS)
Atomic force microscopy (AFM)
Powder X-ray diffraction (PXRD)
Single-crystal X-ray diffraction (SCXRD)
Thermogravimetric analysis (TGA)
Differential scanning calorimetry (DSC)
X-ray photoelectron spectroscopy (XPS)
Inductively-coupled plasma optical emission spectroscopy (ICP-OES)
Dynamic light scattering (DLS)
Device Fabrication and Testing
To fabricate devices, we use the shared facilities generously provided by the SOS lab (Prof. Vinich Promarak) and the EDM lab (Prof. Pichaya Pattanasattayavong) at VISTEC. The facilities are equipped with 2 glovebox trains, 1 thermal evaporator, and various optical and electrical characterization facilities that allow us to construct and test solar cells, light-emitting diodes (LEDs), photodetectors, transistors, and other optoelectronic devices.
