BEST SEMICONDUCTOR MATERIAL EVER FOUND?

-

Talking about semiconductors the first and most widely used semiconductor that comes to our mind is silicon, but is silicon the best semiconductor?

A team of researchers has discovered what the Massachusetts Institute of Technology calls the “best semiconductor material ever found,” even better than silicon, the material used in just about every computer chip on earth


Let's know a little about semiconductors. A semiconductor is a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects.


Silicon is one of the most abundant elements on Earth, and in its pure form, the material has become the foundation of much of modern technology, from solar cells to computer chips. But silicon’s properties as a semiconductor are far from ideal.


For a thought, is there any other Semiconductor that is better than Silicon? Well, a recent study done by an MIT professor has proved that cubic boron arsenide performs better than silicon at conducting heat and electricity this discovery has a lot of potential and might replace the use of silicon as a semiconductor. Although silicon lets electrons whizz through its structure easily, it is much less accommodating to “holes”—electrons’ positively charged counterparts—and harnessing both is important for some kinds of chips. Furthermore, silicon is not very good at conducting heat, which is why overheating issues and expensive cooling systems are common in computers. Cubic Boron arsenide overcomes these limitations.




More work will be needed to determine whether cubic boron arsenide can be made in a practical, economical form, much less replace the ubiquitous silicon. But even in the near future, the material could find some uses where its unique properties would make a significant difference, the researchers say.


All-in-all we know for a fact that in the future computers are going to get exponentially efficient and fast! Also due to the upcoming EV industry, there will be a great increase in semiconductors. Adding to it due to lesser silicon ores in India it will be a potential replacement.

Honeycomb Structure - The Natures Phenomenon

Most of the people have seen a honeycomb , and also the hexagonal structure which it resembles. But we have never given it a thought that why Hexagonal??? Lets explore the significance of this hexagonal structure and relate it to material science . A material with honeycomb structure has minimal density and relatively high out of plane compression properties. Man-made honeycomb structured materials are usually made up by layering a material between two thin layers that provide great strength in tension. credits:- https://www.plascore.com/honeycomb/honeycomb-panels/ The above image shows what exactly happens inside a single honeycomb layer. Honeycomb panel strength works an I beam . The core acts like a vertical element and the facing acts like flange. This combination provides a very high shear strength. Thicker the core , greater will be the strength of material. This kind of material comes under the category of composites. credits:- https://www.plascore.com/honeycomb/honeycomb-panels...

Self-Healing Concrete

Introduction Concrete is one of the most widely used construction materials on earth. But concrete has a flaw, its low tensile strength. It needs to be reinforced with the help of steel or iron rods to compensate for its low tensile strength. In turn, concrete protects the steel from corrosion. But when cracks form in concrete, the rods come in contact with the atmosphere, and their corrosion harms the structure's integrity.  Here comes the idea of self-healing concrete because if we fill the cracks formed in the concrete, then the next step of corrosion of rods will not occur. This self-healing will not lead to harm to the structure's integrity. First let’s see about concrete’s own self-healing properties Autogenous self-healing concrete Concrete in itself processes naturally specific autogenous healing properties. The healing activity in this method initiates because of the hydration of the clinker's minerals present in it. Here the unhydrated cement particles work as a h...
