Approaching the Intrinsic Properties of Moiré Structures Using Atomic Force Microscopy Ironing
Swaroop Kumar Palai, Mateusz Dyksik, Nikodem Sokolowski +12
Stacking monolayers of transition metal dichalcogenides (TMDs) has led to the discovery of a plethora of new exotic phenomena, resulting from moiré pattern formation. Due to the at…
High spatial resolution charge sensing of quantum Hall states
Cheng-Li Chiu, Taige Wang, Ruihua Fan +5
Charge distribution offers a unique fingerprint of important properties of electronic systems, including dielectric response, charge ordering and charge fractionalization. We devel…
Quantifying the local mechanical properties of twisted double bilayer graphene
Alessandra Canetta, Sergio Gonzalez-Munoz, Viet-Hung Nguyen +13
Nanomechanical measurements of minimally twisted van der Waals materials remained elusive despite their fundamental importance for device realisation. Here, we use Ultrasonic Force…
Revealing flat bands and hybridization gaps in a twisted bilayer graphene device with microARPES
Zhihao Jiang, Kimberly Hsieh, Alfred J. H. Jones +7
Controlling the electronic structure of two-dimensional materials using the combination of twist angle and electrostatic doping is an effective means to induce emergent phenomena.…
Engineering the strain and interlayer excitons of 2D materials via lithographically engraved hexagonal boron nitride
Yu-Chiang Hsieh, Zhen-You Lin, Shin-Ji Fung +11
Strain engineering has quickly emerged as a viable option to modify the electronic, optical and magnetic properties of 2D materials. However, it remains challenging to arbitrarily…
