Pt-wedge squeegee cleaning of two-dimensional materials and heterostructures
Emine Yegin, Doruk PehlivanoÄlu, T. Serkan Kasırga
The surface of ultra-thin materials plays a crucial role in determining the properties. This is particularly important in two-dimensional (2D) materials where the surface-bulk dist…
Ionic transport in spontaneously ion-intercalated van der Waals layered structures
Ata Utku Ãzkan, Talip Serkan Kasırga, Aykut ErbaÅ
Understanding ionic transport under strong confinement is crucial for the design of next-generation energy, catalytic, and information-processing materials; however, repeated field…
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…
In-Situ Growth and Ionic Switching Behavior of Single-Crystalline Silver Iodide Nanoflakes
Amir Parsi, Abdulsalam Aji Suleiman, Doruk PehlivanoÄlu +3
Silver iodide (AgI) is a prototypical superionic conductor, undergoing a first-order phase transition at 147 Celsius that enables rapid ionic transport through its lattice, making…
An extensive thermal conductivity measurement method based on atomic force microscopy
T. Serkan Kasırga, Berke Köker
Heat transport in low-dimensional solids can significantly differ from their bulk counterpart due to various size-related effects. This offers rich heat transport phenomena to emer…
Photoluminescence enhancement at the vertical van der Waals semiconductor-metal heterostructures
Hafiz Muhammad Shakir, Abdulsalam Aji Suleiman, Kübra Nur Kalkan +8
Excitons in monolayer transition metal dichalcogenides (TMDCs) offer intriguing new possibilities for optoelectronics with no analogues in bulk semiconductors. Yet, intrinsic defec…
