Research Highlight

Schematic representation of possible binding configurations of butadiene monoxide on Si(111)-(7x7)

Adsorption of butadiene monoxide on Si(111)-(7 x 7) has been scrutinized by high-resolution electron energy loss spectroscopy (HREELS), scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The experimental results indicate that surface reaction occurs through a [2+2]-like cycloaddition, which is further supported by the DFT studies.
