title: Note: Fiber optic transport probe for Hall measurements under light and magnetic field at low temperatures: Case study of a two dimensional electron gas.
abstract: A fiber optic based probe is designed and developed for electrical transport measurements in presence of quasi-monochromatic (360-800 nm) light, varying temperature (T = 1.8-300 K), and magnetic field (B = 0-7 T). The probe is tested for the resistivity and Hall measurements performed on a LaAlO3-SrTiO3 heterointerface system with a conducting two dimensional electron gas.
