Our recent paper was accepted as a Cover Page in ACS Applied Nano Materials, Congratulations​

​Congratulations for our graduated PhD students in 2018: Idris Ajia and Mufasila Muhammed​​​

In article 1703176 ''Enhanced Performance of MoS2 Photodetectors by Inserting a ALD-Processed TiO2 Interlayer'' our group reports the use of an atomic layer-deposited TiO2 interlayer between exfoliated MoS2 and electrode to enhance the performance of moS2 photodetectors. The TiO2 interlayer is inserted through 20 cycled-atomic layer depositions, leading to significant enhancements in the photo-reponsivity and response-recovery time.

Our PhD student Tahani Flemban passed her defense​
