Yufei Li, Thuc Mai, Mohammed Karaki, Evan Jasper, Kevin Garrity, Chase Lyon, Daniel Shaw, Timmothy DeLazzer, Adam Biacchi, Rebecca Dally, Daniel Heligman, Jared Gdanski, Tehseen Adel, Maria Munoz, Alex Giovannone, Amit Pawbake, Clement Faugeras, Jeffrey Simpson, Kate Ross, Nandini Trivedi, Yuanming Lu, Angela R. Hight Walker, Rolando Valdes Aguilar

In magnetically ordered materials with localized electrons, it has been known for a long time [1–3] that the fundamental interactions are due to exchange of electrons. In most cases only the interaction between pairs of spins in neighboring atoms is taken

Quantum Hall Transport Measurements of Lateral p-n Junctions Formed via Precise Spatial Photodoping of Graphene/hBN Heterostructures

Angela Hight Walker, Thuc Mai, Maria Munoz, Curt Richter

We spatially dope heterostructures composed of 2-dimensional (2D) materials to modify devices in-operando for custom functionalities, such as lateral p-n-p junctions. After optically photodoping an hBN/Graphene/hBN heterostructure, we measure the detailed
