Porphyrin Nanoribbon Based Spin Filtering Device
Advancement in molecular electronics opens up another new domain with new possibility of realizing its spin-polarized version, which is called molecular spintronics. This novel domain has a range of applications such as high-capacity storage devices and quantum computers. Several contemporary researchers have considered porphyrin molecules and its derivatives as a potential candidate for molecular devices. Here, using the first principle calculations, we have proposed a porphyrin nanoribbon-based system for spin-filtering application. Such system shows robust half-metallicity and also exhibits itinerant magnetism. Our calculated spin transport properties exhibit that our device can give 100% spin-polarizing efficiency which is very promising for next generation spin-filtering applications.
