Writing in Nano Letters a team led by Professor Chih-Kang Shih from the University of Texas at Austin studied the electronic structures of single layer transition metal dichalcogenides WSe2 and WS2, by scanning tunneling spectroscopy. It is generally well understood within academia that monolayer semiconductor transition metals dichalcogenides, such as WS2, WSe2, Read more…
In a paper published on arXiv teams from the University of Manchester and University College London, report superconductivity in graphene when intercalated with calcium. In this work our hexagonal boron nitride crystals were also used, as a physical spacer for monolayer graphene flakes. The high purity of our crystals and large Read more…
Tungsten diselenide is another layered transition metal dichalcogenide. Like more of the other TMDCs, it is a semiconductor with a band gap in the infrared region. In this article we review the Raman of WSe2 monolayer. Like MoS2 and WS2, the lattice structure of WSe2 is also trigonal prismatic, while Read more…
Tungsten ditelluride (WTe2) is yet another member of the transition metal dichalcogenide family. Unlike other dichalcogenides, tungsten telluride is a semi-metal. In 2015, a Nature [1] paper reported a non-saturating magnetoresistance in this compound which makes it an exciting systems for fundamental transport studies. As with other layered systems, Raman spectroscopy Read more…
In this article we review the WS2 Raman spectrum. Its Raman spectrum is quite similar to it’s dichalcogenide neighbour material, molybdenum. The Raman spectrum of bulk WS2 has two prominent peaks: an in-plane (E2g) mode located around 350cm-1 and an out-of-plane (A1g) mode which is located at 420cm-1. The in-plane mode Read more…
In this blog post, we briefly describe the molybdenum disulfide’s, MoS2, Raman spectrum. Like graphene, single-layer and few-layer molybdenum disulphide (moly) has distinctive signatures in its Raman spectrum. first, let’s discuss the Raman spectrum of bulk MoS2. The Raman spectrum of bulk MoS2 has two prominent peaks: an in-plane (E2g) mode Read more…
