Resistivity measurements of a few-layer black phosphorus (bP) crystal in parallel magnetic fields up to 45 T are reported as a function of the angle between the in-plane field and the source-drain (S-D) axis of the device. The crystallographic directions of the bP crystal were determined by Raman spectroscopy, with the zigzag axis found within 5° of the S-D axis, and the armchair axis in the orthogonal planar direction. A transverse magneto-resistance (TMR) as well as a classically-forbidden…

Evidence of Josephson coupling in a few-layer black phosphorus planar Josephson junction
Setting up strong Josephson coupling in van der Waals materials in close proximity to superconductors offers several opportunities both to inspect fundamental physics and to develop novel cryogenic
Black Phosphorus n-Type Doping by Cu: A Microscopic Surface Investigation
We study surface charge transfer doping of exfoliated black phosphorus (bP) flakes by copper using scanning tunneling microscopy (STM) and spectroscopy (STS) at room temperature. The tunneling
Ohmic contact engineering in few-layer black Phosphorus field effect transistors
Achieving good quality Ohmic contacts to van der Waals materials is a challenge, since at the interface between metal and van der Waals material, different conditions can occur, ranging from the
A Perspective on Recent Advances in Phosphorene Functionalization and Its Applications in Devices
The aim of this review is to summarize the state of the art in this subject and to present the most recent results in the preparation, functionalization, and use of phosphorene and its decorated derivatives.
Ohmic contact engineering in few-layer black Phosphorus: approaching the quantum limit.
Ni results to provide the lowest contact resistance to bP and minimum scattering between different devices, and the best devices approach the quantum limit for contact resistance both for Ni and for Ti contacts.


Large and Anisotropic Linear Magnetoresistance in Single Crystals of Black Phosphorus Arising From Mobility Fluctuations
It is revealed that the large linear MR of layered BP in fact follows a three-dimensional behavior rather than a two-dimensional one, which has implications to both the fundamental understanding and magnetoresistive device applications of BP.

The longitudinal magnetoresistance is easier to analyse than the transverse magnetoresistance, and it is used here to study how the theoretically predicted behaviour depends on the details of the
Axial anomaly and longitudinal magnetoresistance of a generic three dimensional metal
We show that the emergence of the axial anomaly is a universal phenomenon for a generic three-dimensional metal in the presence of parallel electric (E) and magnetic (B) fields. In contrast to the
High-mobility transport anisotropy and linear dichroism in few-layer black phosphorus
A detailed theoretical investigation of the atomic and electronic structure of few-layer black phosphorus (BP) is presented to predict its electrical and optical properties, finding that the mobilities are hole-dominated, rather high and highly anisotropic.
Longitudinal magnetoresistance in the Extreme Quantum Limit in nonparabolic semiconductors
Abstract We calculate the Longitudinal Magnetoresistance in the Extreme Quantum Limit (ħΩc ⪡ kBT) for a nondegenerate n-type InSb sample at low temperatures when the dominant energy and momentum loss
Two-dimensional magnetotransport in a black phosphorus naked quantum well
This work fabricates bP-naked quantum wells in a back-gated field effect transistor geometry and demonstrates that 2D electronic structure and 2D atomic structure are independent, advantageous for materials that become increasingly reactive in the few-layer limit such as bP.
Colossal magnetoresistance in an ultraclean weakly interacting 2D Fermi liquid.
How this colossal magnetoresistance effect cannot be attributed to the spin degree of freedom or localization physics, but most likely emanates from strong magneto-orbital coupling between the two-dimensional electron gas and the magnetic field is discussed.

It is shown that in the hopping regime, the low-field magnetoconductance is always positive, and anisotropic in sufficiently thin films, and this feature is suggestive of a nonlocal (orbital) mechanism.
Longitudinal Negative Magnetoresistance and Magnetotransport Phenomena in Conventional and Topological Conductors.
It is shown that in a certain range of parameters such a phenomenon can also exist in conventional centrosymmetric and time-reversal invariant conductors, lacking topological protection of the electron spectrum and the chiral anomaly.
Highly anisotropic and robust excitons in monolayer black phosphorus.
The experimental observation of highly anisotropic, bright excitons with large binding energy in monolayer black phosphorus opens avenues for the future explorations of many-electron physics in this unusual two-dimensional material, but also suggests its promising future in optoelectronic devices.
