Summary on Grant Application Form |

The aim is to understand the factors which influence the packing of polyaromatic and macrocylic molecules (e.g. perylenes, anthracenes, naphthalenes, phthalocyanines, oligothiophenes) on metal and semiconductor surfaces. Surface vibrational spectroscopies and scanning tunnelling microscopy, supported by LEED and XPS, will be used to characterise the bonding, molecular orientation an lateral order in sub-monolayer and multilayer thin films. The contrast between adsorption on metal surfaces, where corrugation effects are expected to be relatively weak, and semiconductor substrates with a propensity for localised bonding, will be the focus of experiments at St. Andrews and Imperial College respectively. We will investigate the effects of temperature and coverage in controlling the order and crystallinity in the sub-monolayer regime for a range of molecules and substrates. Strategic functionalisation of the molecules will play an important role in controlling the 2D molecular architecture of these systems; this will be investigated and exploited to control the growth of ultra-thin films exhibiting a high degree of order both laterally and in the growth direction. Finally we will investigate the stability of the structures to electron beam damage; functionalities will be selected which offer the best compromise between optimum molecular packing and multilayer crystalline order and minimal beam damage.
