Graphene + Boron Nitride heterostructures Jarillo

Today, it's now understood that silicon dioxide, the most common substrate material for graphene, limits the performance of graphene devices and obscures interesting physics. This is thought to be caused by the roughness of the SiO2 substrates, which induce corrugations in the graphene, as well as charge traps in the SiO2 which results in inhomogeneous doping.

[PDF] The chemistry of two

Ultrathin two-dimensional nanosheets of layered transition metal dichalcogenides (TMDs) are fundamentally and technologically intriguing. In contrast to the graphene sheet, they are chemically versatile. Mono- or few-layered TMDs - obtained either through exfoliation of bulk materials or bottom-up syntheses - are direct-gap semiconductors whose bandgap energy, as well as carrier type (n- or p

RESEARCH GALLERY

We synthesize graphene via chemical exfoliation from bulk graphite, chemical vapor deposition, and silicon sublimation. The majority of our work currently focuses on epitaxial graphene (graphene grown via silicon sublimation), which is an excellent substrate for synthesis of van der Waals heterostructures.

Antimonene Allotropes α

22 Finding electrochemical energy storage systems having high energy densities, long lives, reduced masses, and smaller sizes along with environmental compatibility, cost-effectiveness, and worldwide consumer allocation has been an outstanding problem.(1−6) Alkali ion batteries, especially lithium-ion batteries (LIBs), are in high demand due to their intriguing structural and chemical features.

Non

Noncovalent synthesis of stable heterostructures (graphene-BN, MoS2-graphene) of layered materials has been accomplished by a ternary host–guest complex as a heterocomplementary supramolecular motif. Besides being reversible, this supramolecular strategy to generate heterostructures may find uses in many situations.

Graphene oxide – Jiaxing Huang Group

Graphite oxide sheets, now called graphene oxide (GO), are typically made from chemical exfoliation of graphite by reactions that have been known for 150 years. Interest in this old material has resurged since 2004 as it is considered a promising solution-processable precursor for bulk production of graphene.

OSA

Position-sensitive detectors (PSDs) based on the lateral photo effect have been widely used in diverse applications including optical engineering, aerospace, and military fields. With increasing demands for long-working-distance, low-energy-consumption, and weak-signal-sensing systems, the poor responsivity of conventional silicon-based PSDs has become a bottleneck limiting their applications
