Abstract: Spin electronics is an emerging field that has huge potential to revolutionize the IT industry and next-generation electronic applications. Over the past two decades, spin currents (consisting of spin-polarized electrons) have led to a colossal expansion of memory storage capacity in computers through the giant magnetoresistance effect (Nobel Prize in Physics 2007). Beyond this major advancement, spin currents exhibit outstanding prospects for ultralow power and faster spin-electronics. For exploring such prospects, the new class of two-dimensional (2D) materials, that are atomically thin crystals with thickness ~few Å-nm have emerged as ideal systems. A classic example of such materials is graphene, where spin currents can travel over tens of microns at room temperature, up to hundred times longer than in normal metals. In this lecture, first, I will present how understanding magnets has led to the development of the fascinating field of spintronics. Following this, I will introduce how graphene and graphene-like other 2D materials provide unprecedented means to investigate spin currents for realizing novel spin-logic and memory components.

The lecture, which is a teaching test for those who applied to be admitted as an associate professor, will be followed by students and others with knowledge at the undergraduate level in the subject, but may also be of interest to a wider audience. The lecture will last for 45 minutes and will be given in English.
