6 课题介绍（Introduction of the thesis proposal)
课题名称
Contacting  molecules on metallic pads at the nanoscale

In molecular electronics, one of the most remaining challenge concerns the understanding of electronic contacts at the nanoscale. Indeed, while contacting an individual molecule to a single metallic atom as been investigated, controlling the electronic contacts of individual molecules on the side of a metallic pad remains unexplored. Although crucial, this research topic needs to be performed in the right experimental conditions for which the electronic structural changes of the contacted molecule can be explored as well as the transport through it. This PhD subject aims to perform this research via the use of a scanning tunneling microscope (STM) working at low temperature. After the growth of silicide pads (Co or Ni) on the Si(100) surface, the PhD student will explore the passivation of the surrounding bare silicon surface to allow the electronic decoupling between the surface and the molecule. Then, several types of molecules will be adsorbed on the Si(100):H surface and pushed towards the metallic pads with the STM to investigate how the electronic contact can be performed between the molecule and the silicide islands. This will be realized via various molecular conformations and arrangements. The PhD candidate should have very good experimental skills, good knowledge in physical chemistry and solid state physics. He/she will be strongly involved in the analysis of the experimental data and the modeling of physical phenomena. Different types of simulations can be achieved at ISMO or through external collaborations.

第二个课题：
课题名称：Charge transfer control in small molecular assemblies
课题介绍：

The processes of charge transfer (CT) are at the heart of our daily life as they trigger a large amount of physical or chemical phenomena that include electronic transport, solar cell, organic emitting devices, spintronics or biological systems. Whether CT involve photoinduced excited states or ionic species in a solvent-like environment, the perturbation and the scale at which the CT processes are described is of crucial importance but yet still not well explained. Scanninng tunneling microscopy can answer  these needs by assembling molecules on insulating surfaces to obtain molecular architectures which properties (including optical, electronic, or magnetic) can be explored via the study of charge transfer induced by tunnel electrons. In this context, the purpose of the thesis will be to study the CT in simple molecular circuits formed by a few molecules whose individual electronic properties will be pre-selected from several molecular families (metal-porphyrins or phthalocyanines). For this, we will use a scanning tunneling microscope working in ultrahigh vacuum and at low temperatures to allow the assembly and analysis at the atomic scale of the molecular architecture. The molecules will be initially deposited on an insulating epitaxial layer (CaF2) fabricated on the Si(100) surface which will allow guiding the molecules along stripes. The aim will be to transfer one or several electrons from one side of the circuit to the other. The circuit will be activated by the STM tip as well as the analysis of the conformation change in the circuit. The PhD candidate should have very good experimental skills, good knowledge in physical chemistry, solid state physics. He/she will be strongly involved in the analysis of the experimental data and the modeling of physical phenomena. Different types of simulations (DFT) can be achieved at ISMO or through external collaborations.
