Welcome!
Welcome to the homepage of the research group “Inorganic Materials Chemistry” IMC of Prof. Dr. Anjana Devi.
Our group focuses on the development, synthesis and evaluation of high-performance precursors for vapor phase deposition processes namely chemical vapor deposition (CVD), atomic layer deposition (ALD) and molecular layer deposition (MLD).
We collaborate with scientists from various disciplines (Physics, Chemistry and Engineers) and our goal is to develop nanostructured materials for different applications ranging from microelectronics, sensors, dielectrics, barrier coatings, spintronics, optics, catalysis etc.

With his research, Mr. Ameloot builds a bridge between the unique properties of MOFs and their application in microelectronics through the development of new chemical vapor deposition techniques.
After his talk, we had a fruitful discussion about CVD techniques, thin film growth mechanisms and precursor chemistry and how we can benefit from each other to increase the scientific outcome.

The granted 4 million euros by the BMBF is to acquire a unique cluster tool that integrates ALD, ALE, PECVD, RIE and in-situ plasma diagnostics. This state-of-the-art tool will be employed for the deposition of 2D-materials, etching, passivation and subsequently device structures will be fabricated that will play an important role in the future for various applications in the field of microelectronics, optoelectronics, sensors, energy etc.
The interdisciplinary research activities starting from precursors chemistry to materials development followed by process diagnostics and device fabrication will be the key to realize the goals of various projects that will be carried using the “ForLab- PICT2DES” cluster tool at RUB.

More information will follow soon.
The main research objectives of the project are the growth and integration of 2D-materials such as TMDs for flexible electronics. The IMC group will develop new ALD and CVD processes for 2D materials/TMDs using novel precursor chemistry combinations. Together with the engineering department, the group will investigate the electrical and topographical properties of the TMDs layers/high-k oxides for device fabrication and integration of 2D-materials into functional devices.

Rob Ameloot visiting our group
Today, Rob Ameloot visited our group to give a fascinating talk about “Metal-organic framework chemical vapor deposition (MOF-CVD)”. He is the leader of the Ameloot Group at the KU Leuven, Belgium.With his research, Mr. Ameloot builds a bridge between the unique properties of MOFs and their application in microelectronics through the development of new chemical vapor deposition techniques.
After his talk, we had a fruitful discussion about CVD techniques, thin film growth mechanisms and precursor chemistry and how we can benefit from each other to increase the scientific outcome.
