16. Exploring Topological Transitivity in Families of Functions

Author

Singh, Anil and Lal, Banarsi

Subjects
Mathematics - Complex Variables
Abstract

We have established various criteria for the topological transitivity of families of continuous (holomorphic) functions. Furthermore, by leveraging the properties of expanding families of meromorphic functions, we offer an alternative proof of Montel's three point theorem.

Abstract

The interplay of electrons with a chiral medium has a diverse impact across science and technology, influencing drug separation, chemical reactions, and electronic transport. In particular, such electronchirality interactions can significantly affect charge and spin transport in chiral conductors, ranging from bulk semiconductors down to individual molecules. Consequentially, these interactions are appealing for spintronic manipulations. However, an atomistic mapping of the different electron chirality interactions and their potential for spintronics has yet to be reached. Here, we find that single molecule junctions based on helicene molecules behave as a combined magnetic diode and spin valve device. This dual functionality is used to identify the coexistence of different electron chirality interactions at the atomic scale. Specifically, we find that the magnetic diode behavior arises from an interaction between the angular momentum of electrons in a chiral medium and magnetic fields, whereas the spin valve functionality stems from an interaction between the electron spin and a chiral medium. The coexistence of these two interactions in the same atomic scale system is then used to identify the distinct properties of each interaction. This work uncovers the different electron chirality interactions available at the atomic level. The found concurrent existence of such interactions can broaden the available methods for spintronics by combining their peculiar functionalities.

Abstract

The exceptional properties of two-dimensional (2D) magnet materials present a novel approach to fabricate functional magnetic tunnel junctions (MTJ) by constructing full van der Waals (vdW) heterostructures with atomically sharp and clean interfaces. The exploration of vdW MTJ devices with high working temperature and adjustable functionalities holds great potential for advancing the application of 2D materials in magnetic sensing and data storage. Here, we report the observation of highly tunable room-temperature tunneling magnetoresistance through electronic means in a full vdW Fe3GaTe2/WSe2/Fe3GaTe2 MTJ. The spin valve effect of the MTJ can be detected even with the current below 1 nA, both at low and room temperatures, yielding a tunneling magnetoresistance (TMR) of 340% at 2 K and 50% at 300 K, respectively. Importantly, the magnitude and sign of TMR can be modulated by a DC bias current, even at room temperature, a capability that was previously unrealized in full vdW MTJs. This tunable TMR arises from the contribution of energy-dependent localized spin states in the metallic ferromagnet Fe3GaTe2 during tunnel transport when a finite electrical bias is applied. Our work offers a new perspective for designing and exploring room-temperature tunable spintronic devices based on vdW magnet heterostructures.
