Surface science (spectroscopy, microscopy, scattering) and organic MBD capabilities  
fully integrated with N2 glove boxes dedicated to solution processing, fabrication and testing of 
organic electronic, nanoelectronic and photovoltaics.

We use a w​ide array of additional characterization techniques in KAUST's shared facilities, including AFM, SEM, TEM/STEM/EFTEM, Raman, FTIR, NMR. In addition, we also use KAUST's premier scientific visualization facilities as a tool for understanding complex molecular crystalline structures.

We also have several active proposals at synchrotron X-ray radiation sources in the US, including at ALS (LBNL, Berkeley), SSRL (SLAC, Stanford), and CHESS (Cornell), where the Amassian group performs a variety of static and time-resolved scattering, spectroscopy and microscopy measurements on organic semiconductors and colloidal quantum dots used in electronics and in solar energy and low-cost solution processing techniques used to fabricate devices thereof.
