Download Angle-Resolved Photoemission Spectroscopy Studies of 2D Material Heterostructures Book in PDF, ePub and Kindle
This book focuses on angle-resolved photoemission spectroscopy studies on novel interfacial phenomena in three typical two-dimensional material heterostructures: graphene/h-BN, twisted bilayer graphene, and topological insulator/high-temperature superconductors. Since the discovery of graphene, two-dimensional materials have proven to be quite a large “family”. As an alternative to searching for other family members with distinct properties, the combination of two-dimensional (2D) materials to construct heterostructures offers a new platform for achieving new quantum phenomena, exploring new physics, and designing new quantum devices. By stacking different 2D materials together and utilizing interfacial periodical potential and order-parameter coupling, the resulting heterostructure’s electronic properties can be tuned to achieve novel properties distinct from those of its constituent materials. This book offers a valuable reference guide for all researchers and students working in the area of condensed matter physics and materials science.

Download Magnetic Proximity Effect Inside Heterostructures of 2D Materials and Thin Films Adjacent to Magnetic Insulators Book in PDF, ePub and Kindle
The magnetic proximity effect (MPE) has generated a lot of interest recently due to its ability to introduce magnetic order into otherwise non-magnetic systems. It can be realized in 2D material stacks as well as inside 3D material thin film heterostructure. The work in this thesis explores MPE inside a variety of heterostructures using multiple measurement techniques. It demonstrates the first realization of MPE inside a thin film of Pt from a ferrimagnetic insulator CoFe2O4. Next, it experimentally demonstrates a novel growth method for synthesizing high quality thin films of topological Dirac semimetal Na3Bi on Al2O3 substrate, and further extends this growth method to synthesize the first topological Dirac semimetal/magnetic insulator heterostructure of Na3Bi/CoFe2O4. Finally, it lays the groundwork for ambitious studies of MPE inside 2D material/magnetic insulator heterostructures using angle-resolved photoemission spectroscopy. This is accomplished by a new process of transferring flakes of 2D materials on top of freshly deposited thin films while inside an ultra-high vacuum environment.

Download Micro-focus ARPES of Operating 2D Devices Book in PDF, ePub and Kindle
With the advent of two-dimensional (2D) materials came a library of new systems that not only individually host novel states of matter but are naturally suited to being stacked into heterostructures – a virtually limitless space of possible geometries for study. The incorporation of electrical contacts transforms these heterostructures into 2D electrical devices wherein electronic behavior can be simultaneously probed and tuned by locally applied electric fields. This thesis presents pioneering studies of the electronic band structure in such devices in-operando using sub-micrometer angle-resolved photoemission spectroscopy (micro-ARPES), a surface-sensitive technique already perfectly suited to probe the electronic states in these 2D systems made more powerful by the addition of in-situ control of carrier densities and local electric fields.Following a brief background review of 2D materials and ARPES, I will show how with careful sample design and preparation micro-ARPES was applied for the first time to artificially stacked structures of prototypical 2D materials, graphene and atomically thin semiconducting transition metal dichalcogenides (TMD). From there, I will demonstrate how in-situ control of an electrostatic back gate voltage alleviates a fundamental limitation of ARPES as a probe of only occupied states and study the electronic landscape in two-terminal TMD field-effect transistor devices as a function of applied electric field and doping. I will then take a detour to discuss the possible effects of relative crystallographic alignments in heterostructures on the micro-ARPES spectra, which ultimately stem from a combination of moiré effects and electron diffraction. I will then turn to gated devices with monolayer WTe2 and study the bands as a function of doping and temperature to shed light on the of its unusual insulating state below 100K which interplays with topologically insulating and superconducting behavior recently shown in transport measurement. Finally, I will conclude with a brief discussion of the outlook for micro-ARPES of 2D materials in devices under operation.
