We perform single-molecule junction experiments. Our long-term goal is to understand and control charge transport across molecules. As a first step (first two years) within the priority program we will focus on methodological improvements. In this project we want to control charge states in single-molecule junctions. We will approach this goal by two means: First, we will redesign the experimental setup such that an electrostatic gate is available. Second, we will design and synthesize molecules, which provide a well-defined charge state, accessible by finite voltages in a two terminal experiment. We expect an interplay of electrostatic effects driven by asymmetric bias voltage, and by the gate voltage. The starting parameters have to be carefully tuned by a suitable choice of the molecule. We are further interested in the question how the variation of the charge state is associated with changes in the geometry of the molecule.

我们进行单分子结实验。我们的长期目标是了解和控制分子间的电荷传输。作为优先方案的第一步（头两年），我们将侧重于方法上的改进。在这个项目中，我们希望控制单分子结中的电荷状态。我们将通过两种方法来实现这一目标：首先，我们将重新设计实验装置，使静电门可用。其次，我们将设计和合成分子，它提供了一个明确的电荷状态，在两端实验中通过有限的电压访问。我们预期的相互作用的静电效应驱动的不对称偏置电压，并通过栅极电压。必须通过适当选择分子来仔细调整起始参数。我们更感兴趣的问题是电荷状态的变化如何与分子几何形状的变化相关联。
