New approach reliably integrates 2D semiconductors with dielectrics

Two-dimensional (2D) semiconductor materials could enable the development of smaller yet highly performing electronic components, thus contributing to the advancement of a variety of devices. While significant strides have been made in the synthesis of 2D semiconductors with advanced electronic properties, their clean transfer onto substrates and reliable integration in real devices has so far proved challenging. Researchers at Peking University, the Beijing Graphene Institute and other institutes in China have recently developed a new method to integrate 2D semiconductors with dielectric materials, which are insulating materials that help control the flow of electric charge in devices. Their approach, outlined in a paper published in Nature Electronics, entails the epitaxial growth of an ultra-thin dielectric film on a graphene-covered copper surface, which subsequently enables its transfer onto various substrates with minimal defects.

Ever wondered how the material between a capacitor's plates affects its ability to store charge? ⚡️

Dive into our latest article, "Understanding the Effect of Dielectrics on Capacitance and Capacitor Combinations," to explore how dielectrics increase capacitance and how to calculate the equivalent capacitance for series and parallel circuits.

Whether you're a student or a hobbyist, this guide will demystify one of the most fundamental concepts in electronics. Read the full article now!

This week I continued to venture into the realm of nonlinearities by learning about the Lorentz model followed by the Drude model for metals.

It was fun employing the whole "statistical ensemble" trick to relate the microscopic dipole moments of individual atoms being subjected to an applied Electric Field to the macroscopic property of Material Polarization and further towards the Electric Flux Response of a material.

Once again, complex numbers rear their heads and there's growing pains in understanding the physical significance behind "complex dielectric" with the "real permittivity" all while trying to connect it with notions of conductivity in terms of both free space responses and material responses contributing to the total Electric Flux.

It is kinda neat how the complex refractive indexes extinction coefficient can be used to ??? Let us see where a materials absorption is highest near points of resonance?

And furthermore, a interesting connection to metamaterials was established when I realized that if the resonances of our doped elements are in frequencies way below our materials resonances, we do some cool stuff with the maths.

Something something we can use the dielectric permittivity at DC and at very high (infinity) to calculate the plasma frequency of a metal.

Now my plan is to deep dive into crystal anisotropy, do some numerical examples of tensor rotation, and hopefully that will help me better understand optical components like quarter wave plates and all that stuff.

Would You Eat a Windmill? These Scientists Hope So.

Despite being an excellent source of renewable energy, wind turbines, like most manufactured products, eventually need to be disposed of, for one reason or another. That poses an obviously large problem given their size, but researchers at Michigan State University are working on a novel solution: a newly developed… Read more…
