Enhancing the Efficiency of Semiconductors by Using the Spin of Electrons11 February 2025
In today’s electronics industry, there is a huge demand for faster and more efficient systems to meet the modern IoT systems. The advancement of the semiconductor industry has heavily relied on the manipulation of electrical charges, but controlling the spin degree of freedom has proved to be exceptional. Spintronics, a field focused on studying the spin properties of electrons, has gained a lot of attention due to its potential to enable faster and more efficient devices. The integration of chiral halide perovskite (c-HPs) with traditional III–V semiconductors offer a very transformative effect for spin-based electronics. Semiconductors have been an integral part of the electronics industry due to their ability to manipulate electrical charge but spintronics aims to use the spin of electrons to enable a lot of functionalities.
