    • CVD synthesis and characterization of thin Mo2C crystals 

      Türker, F.; Caylan, Ö. R.; Mehmood, Naveed; Kasırga, Talip S.; Şevik, C.; Cambaz-Büke, G. (Wiley, 2020)
      In this study, we present an investigation on the growth of thin Mo2C crystals via chemical vapor deposition using CH4. Optical microscopy (OM), scanning electron microscopy (SEM), atomic force microscopy(AFM), and Raman ...

    • Electric-field-induced reversible phase transitions in a spontaneously ion-Intercalated 2D metal oxide 

      Rasouli, Hamid Reza; Kim, J.; Mehmood, Naveed; Sheraz, Ali; Jo, M. K.; Song, Seungwoo; Kang, K.; Kasırga, Talip Serkan (American Chemical Society, 2021-05-12)
      Electric field driven reversible phase transitions in two-dimensional (2D) materials are appealing for their potential in switching applications. Here, we introduce potassium intercalated MnO2 as an exemplary case. We ...

    • High elasticity and strength of ultra-thin metallic transition metal dichalcogenides 

      Sheraz, Ali; Mehmood, Naveed; Çiçek, M. M.; Ergün, İ.; Rasouli, H. R.; Durgun, Engin; Kasırga, Talip Serkan (Royal Society of Chemistry, 2021-05-24)
      Mechanical properties of transition metal dichalcogenides (TMDCs) are relevant to their prospective applications in flexible electronics. So far, the focus has been on the semiconducting TMDCs, mostly MoX2 and WX2 (X = S, ...

    • Optoelectronic and thermal properties of metallic transition metal dichalcogenides 

      Mehmood, Naveed (Bilkent University, 2020-11)
      After the successful isolation of graphene monolayer from its bulky counterpart, there has been tremendous advancement in the field of 2D material. Transition metal dichalcogenides(TMDCs) is family of 2D materials comprising ...

    • Photocurrent generation in a metallic transition-metal dichalcogenide 

      Mehmood, Naveed; Rasouli, Hamid Reza; Çakıroǧlu, Onur; Kasırga, T. Serkan (American Physical Society, 2018)
      Photocurrent generation is unexpected in metallic 2D layered materials unless a photothermal mechanism is prevalent. Yet, typical high thermal conductivity and low absorption of the visible spectrum prevent photothermal ...

    • Real time optical observation and control of atomically thin transition metal dichalcogenide synthesis 

      Rasouli, Hamid Reza; Mehmood, Naveed; Çakıroğlu, Onur; Kasırga, T. Serkan (Royal Society of Chemistry, 2019)
      Understanding the mechanisms involved in chemical vapour deposition (CVD) synthesis of atomically thin transition metal dichalcogenides (TMDCs) requires precise control of numerous growth parameters. All the proposed ...

    • Study of anisotropic particles in active bath 

      Mehmood, Naveed (Bilkent University, 2015)
      Brownian (passive) particles undergo random motion due to thermal agitation in the surrounding medium. In recent years, a lot of attention has been devoted to study active Brownian particles, i.e., microscopic particles ...

    • Synthesis of V2 O3 nanoplates for the exploration of the correlated supercritical state 

      Rasouli, Hamid Reza; Mehmood, Naveed; Çakıroğlu, Onur; Sürmeli, Engin Can; Kasırga, T. Serkan (American Physical Society, 2019)
      Peculiar features exist in the stress-temperature phase stability diagram of V2O3, such as a first-order phase transition between the paramagnetic insulating and metallic phases that ends with a critical point, quantum ...

    • Thermal conductivity measurements in nanosheets via bolometric effect 

      Çakıroğlu, Onur; Mehmood, Naveed; Çiçek, Mert Miraç; Rasouli, Hamid Reza; Durgun, Engin; Kasırga, T. Serkan; Aikebaier, Aizimaiti (IOP Publishing Ltd, 2020)
      Thermal conductivity measurement techniques for materials with nanoscale dimensions require fabrication of very complicated devices or their applicability is limited to a class of materials. Discovery of new methods with ...
