Device Technology and Chemical Physics Laboratory

Mission

Throughout the evolution of human societies one of the major drivers that improved the quality of the daily life was the curiosity of humans to unravel the basic operation principles hidden behind state-of-the-art technologies and to eliminate phenomenological understanding.

Gaining deeper insight in physical phenomena produces new Knowledge and advances Science. Knowledge strengthens the skills of individuals while Science improves society in all. Both Knowledge and Science are fundamentally linked to the research mission of the Device Technology & Chemical Physics Lab (DEVTECH&CP Lab), which is the generation of skillful and educated human potential and the acceleration of scientific achievements in the field of nanoengineering and nanotechnology of organic electronic materials. The general goals of the DEVTECH&CP Lab are i) to continuously strive towards excellence by producing ground-breaking and problem-solving results in the field of organic electronic nanomaterials and electrophotonic devices and ii) to capitalize on the human potential available in the academic environment of Cyprus by developing the skills of young researchers and by growing a research culture on the highest standards of professional attitude; that is a problem-oriented approach to scientific work as well as high commitment and dedication to experimental work.

 The Lab strives to continuously gain in-depth insight in the physico-chemical properties of electronically active organic semiconductors (small molecular and polymeric) and to establish rigorous structure-property-performance correlations for promoting knowledge on the properties of organic electronics to a regime beyond the current state-of-the-art. Ultimately the DEVTECH&CP Lab aims to provide useful feedback that can i) guide material designers to formulate rigorous design principles for producing high performance functional materials and ii) contribute in the development of high quality electrophotonic layers for technologically important device platforms such as solar cells, radiation-sensors, organic lasers, and non-volatile memory devices.

 The DEVTECH&CP Lab sets out to embark towards high-vision research projects in the field of nanostructured organic electronic materials and devices and to promote scientific excellence in molecular semiconductors research at the international level, in collaboration with a broad network of research institutions and other academic centers located in Cyprus and in abroad.

Research

The DEVTECH&CP Lab focuses on cutting edge research projects in the field of nano-engineered organic electrophotonic devices by combining a strong expertise in the study of physico-chemical properties of organic materials and the processing of nanostructured composites via solution-based processing protocols with advanced spectroscopic and electro-optical characterization techniques, and with the smart engineering of device architectures. Attention is given on the establishment of rigorous structure-property-performance relationships for the development of optimized photoactive layers systems via solution-deposition techniques such as spin- and dip-coating. Particular emphasis is given on the use of spectroscopic techniques that monitor electronic energy- and charge-transfer processes for providing solutions in current research problems dealing with the protection, the optimization and the sensitization of organic electronic devices. Within this context, research projects are currently ongoing on:

 

  • the study of structural polymorphs in matrices of π-conjugated polymers with particular attention on their effects in the competition between non-geminate charge recombination and charge extraction in organic photovoltaic devices.

 

  • the development of fullerene-free photoactive layers based on low-cost perylene diimide electron acceptors for organic photovoltaic applications.

 

  • the electro-optical characterization of power-generating and light-sensing devices with the use of transient photocurrent and transient photovoltage characterization measurements.

 

  • the study of triplet energy migration and triplet energy transfer processes for the optimization of solid-state organic photon energy up-converters.

 

  • the sensitization of sol-gel-based metal oxides by photon energy up-converting organic composites.

 

  • the correlation of delayed (in the μs time-scale) charge-transfer induced luminescence intensity with charge transport properties of organic photoactive composites.

 

  • the application of phosphorimetric spectroscopy techniques for the study of solution-processed barrier materials that aim to protect organic electronic devices.

 

  • the use of organic polymeric composites for the development of high density non-volatile memory media.
