Synthesis of Ultra-thin Potassium Tungsten Bronze Single Crystals with Optically Contrasting Domains and Resistive Switching
Abdulsalam Aji Suleiman, Amir Parsi, Hafiz Muhammad Shakir +3
Potassium tungsten bronzes (KWO) are nonstoichiometric oxides in which alkali ions, i.e., K+, occupy one-dimensional tunnels of the hexagonal WO6 framework, enabling couple…
High elasticity and strength of ultra-thin metallic transition metal dichalcogenides
Ali Sheraz, Naveed Mehmood, Mert Miraç Çiçek +4
Mechanical properties of transition metal dichalcogenides (TMDCs) are relevant to their prospective applications in flexible electronics. So far, the focus has been on the semicond…
Synthesis, electric-field induced phase transitions and memristive properties of spontaneously ion intercalated two-dimensional MnO
Hamid Reza Rasouli, Jeongho Kim, Naveed Mehmood +5
Two-dimensional (2D) materials are suitable hosts for the intercalation of extrinsic guest ions such as Li+, Na+ and K+ as the interlayer coupling is weak. This allows ion intercal…
Thermal Conductivity Measurements in Nanosheets via Bolometric Effect
Onur Çakıroğlu, Naveed Mehmood, Mert Miraç Çiçek +4
Thermal conductivity measurement techniques for materials with nanoscale dimensions require fabrication of very complicated devices or their applicability is limited to a class of…
Real time optical observation and control of atomically thin transition metal dichalcogenide synthesis
Hamid Reza Rasouli, Naveed Mehmood, Onur Çakıroğlu +1
Understanding the mechanisms involved in chemical vapour deposition (CVD) synthesis of atomically thin transition metal dichalcogenides (TMDCs) requires the precise control of nume…
Photocurrent Generation in a Metallic Transition Metal Dichalcogenide
Naveed Mehmood, Hamid Reza Rasouli, Onur Çakıroğlu +1
Light induced current in two-dimensional (2D) layered materials emerges from mechanisms such as photothermoelectric effect, photovoltaic effect or nonlocal hot carrier transport. S…
