Nanodiamonds are nanometer sized hydrocarbon molecules, which exhibit a diamondlike structure. As for other nanosized carbon materials (e.g. nanotubes or nanoribbons) diamondoids are discussed to exhibit tunable electronic properties[1]. For future applications in nanoelectronics it is therefore inevitable to study the interaction between diamondoids and solid substrates. Here, we studied the structure formation of tetramantane[121] on a close packed metal substrate with low temperature scanning tunneling microscopy. Tetramantane was evaporated at room temperature under UHV conditions onto a clean copper(111) surface using a self-constructed molecule gun. We observed that tetramantane forms islands on copper(111). Furthermore, we discovered different phases within these islands, which show commensurability with the substrate.
