Water soluble Si particles were produced by modifying the surface with mercaptosuccinic acid (MSA). Using the MSA modified Si particle ink, porous-like Si films with resistivities of 10(2) Omega cm were formed by annealing above 260 degrees C. Cur...

Ethoxy-terminated silicon quantum dots (Si QDs) were prepared by a simple ball milling method of bulk Si in ethanol. Size (diameter) and band-gap energy (E-g) were 2.6 +/- 0.3 nm and 2.1 eV by TEM and absorption spectroscopy, respectively. The mai...

A conventional laser microscope can be used to derive the index of refractivity by the ratio of geometrical height of the transparent platelet to the apparent height of the normal incident light for very small crystals in the wide size range. We d...
We show that aqueous inks containing Au nanocrystals that were slightly modified with mercaptosuccinic acid (MSA, IUPAC name: sulfanylsuccinic acid) turn into conductive films after being cured in room-temperature air. Because of the highly hydrop...
