You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Anamul Md Hoque?, PhD student at Quantum Device Physics, Department of Microtechnology and Nanoscience. The seminar is titled ?WS2 nanoribbon and all-CVD MoS2-graphene FETs for nanoelectronic devices??. Abstract: It has been 75 years since the invention of the transistor that heralded the modern electronic age. Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDCs) have attracted tremendous interest for high-performance and energy-efficient nanoscale field-effect transistors (FETs). Despite recent advances in down-scaling the gate and channel lengths, the fabrication of sub-25 nm narrow channel of TMDC FETs remained challenging. In my talk, I will demonstrate the fabrication of tungsten disulfide (WS2) nanoribbon down to sub-10 nm width. Nanoribbon FETs exhibit good transistor performance, where the transport parameters are governed by the narrow channel effects. In addition, scalable chemical vapour deposition (CVD)-grown MoS2 and graphene FETs are very promising for future nanodevices, especially for flexible solar cells, memory devices, and neuromorphic computing. I will also show transport properties, memristive switching, and Schottky barrier analysis in CVD-grown MoS2 -graphene heterostructure FET devices. These findings open the door for the fabrication of future-generation nanometer-scale transistors, sensors, and optoelectronic devices based on van der Waals semiconductors. The seminar is divided into two parts, where the first part consists of a pure overview of the field and is held on a generally accessible level (10 min). The second part will be more technical (15-20 minutes).

You are welcome to join us in lecture hall Kollektorn, MC2 with fika or on zoom. Our speaker is Vesa Halipi, PhD student at Chemical Biology/LIFE Sciences. The seminar is titled ?Cell derived vesicles ? friends or foes in Alzheimer?s disease???. Abstract: Alzheimer?s disease is a neurodegenerative disorder that causes problems with thinking, memory, and behavior. Abnormal clumps of protein called amyloids play a central role in Alzheimer?s disease. Extracellular vesicles are released by all cells in our bodies and are believed to be important in Alzheimer?s disease, although their exact role is yet to be uncovered. We have studied the effect of extracellular vesicles on the formation of amyloids. The seminar is divided into two parts, where the first part consists of a pure overview of the field and is held on a generally accessible level (10 min). The second part will be more technical (15-20 minutes).
