Single electron detectors. The Aim of the project is to make use of the unique carbon nanotubes properties in single electrons detection performed during the measurements of electronic properties of different kinds of highly resistive molecular systems. Essentially, a nanodevice is composed of a single carbon nanotube coupled to the object under investigation. Such hybrid structure allows in a controllable way to manipulate single electrons in a nanoparticle. What is more, the structure can be exposed to different perturbations such as electric field, illumination or structural modifications in order to examine the changes induced by external factors. Understanding of these properties is the important part of the project since they appear to be an attractive subject of both the fundamental research as well as the applications to nano- and opto- electronics.
Research on graphene. The project concerns the manufacture of single graphene layers using the method of exfoliation. Graphene is deposited directly on the surface of a sample (usually SiO2). Optical measurements (Raman spectroscopy) are used when determining a number of graphene layers and their quality. Epitaxial graphene is also in the domain of our intrest. (ITME). One of the project’s objectives is to develop the method of manufacturing of graphene-based transistors with the insulator substrate. One of the possible applications could also be the use of graphene as an absorbent in photodetectors. Such device could work as the electromagnetic radiation detector operating in a wide spectral range, from the infrared to the ultraviolet.
Photovoltaic nanocells. The main purpose of the project is to develop the innovative photovoltaic nanocell, which would exhibit the much higher efficiency than conventional devices. The new cell is going to be based on carbon nanotubes and semiconducting quantum dots. Understanding of the energy conversion mechanisms in these devices would also lead to improvements in already existing macroscopic photovoltaic cells.The new mechanisms are to be investigated as they appear to be very promising in applications to photovoltaics. It is assumed that incorporating the innovative methods of a cell construction, involving apart from hybrid devices (carbon nanotubes and quantum dots) also a special kind of the plasmonic structures, could introduce new aspects to the object-light interaction analysis.
