Technologies that shape our digital society and their chemical foundation (Materials in electronics and electrical engineering)

Course learning objectives: Our society is deriving more and more into the digital/virtual space. Internet of things, digital revolution, and industry 4.0 are just a few keywords. These concepts are carried by improvements in the hardware, e.g. with increasing potent computational power, described in the famous law of Moore. They are driven by advancements in manufacturing and fabrication technologies, e.g. allowing for a decreasing size of a single transistor in integrated circuits. Another example is the smartphone. Within a decade it overtook conventional mobile phones, integrating a variety of functions and constantly adding more, like the latest bendable screens by Samsung and others. Hidden underneath all these advancements lays progress in electrical engineering, not at last fuelled by new chemistry, physics as well as new capabilities in material science.

The more complex those technologies get the more important it is to emphasise the path towards them, so society don’t lose the understanding for it. Hence, this lecture aims to highlight how we solved fundamental problems to enable the current technologies. The lead question and hook for student’s interest is: What is needed to build a smartphone? Beneath lays the question which materials are used in electrical engineering, how do they work and how are they processed. In the lecture students are confronted with an everyday technology, as requested in the model CHE-BWP2-1: Advanced topics of Chemistry and shall wonder which chemistry and material related science is required and hidden in various function of a smartphone. The lecture will discuss the used materials, their properties, processing, and application in different spots of a smartphone. Further, the lecture shall emphasise the interdisciplinary awareness, here for applied physics and electric engineering.
