Surface Science Tools and Their Application to Nanosystems Like C60 on Indium Phosphide

Electronic properties of C60/InP(001) heterostructures

“…It is used as a material in microwave power devices and as an active layer in optoelectonics. The unique property of C 60 on InP(001) is that thick C 60 films form ordered layers on InP(001) in an fcc (111) structure [1,2]. Therefore, the knowledge of the interface properties of the semiconductor heterostructure is of great interest.…”

“…The band discontinuities of heterojunctions are key design parameters, since the valence and conduction band offsets, E V and E C , determine the transport and confinement properties at the interface. The interaction of C 60 with InP(001)-(2 × 4) has been studied by a number of surface sensitive techniques [1][2][3]. The growth mechanism of C 60 molecules on InP(001) as well as the bonding at the interface were studied by scanning tunnelling microscopy (STM), (high resolution) electron energy loss spectroscopy ((HR)EELS), x-ray and ultraviolet photoelectron spectroscopy (XPS, UPS) and low energy electron diffraction (LEED) [1,2].…”

Nevertheless, publications devoted to the study of the electronic properties of the C 60 /InP(001) interface are rather rare.…”
