Scanning tunneling microscopy investigations of transition metal dichalcogenide 1t-tantalum disulfide and zigzag-shape graphene nanoribbons in ultra-high vacuum
This thesis demonstrates the studies of 1T-TaS2, a member of the transition metal dichalcogenides (TMDCs) family, and wet-chemically synthesized zigzag-shape graphene nanoribbons (GNRs) on hydrogen passivated silicon substrate through scanning tunneling microscopy (STM). Dry contact transfer allows …

Synthesis, characterisation and properties of tantalum based inorganic nanofibres
… is a common theme throughout. High aspect ratio tantalum disulfide, TaS2 nanofibres were prepared from a 1:2 stoichiometric mixture of elemental powders in a one-step synthesis utilising silica ampoules. A surface assisted growth phenomena was investigated and found to significantly increase the …

Elucidation of Charge Density Wave Stability and Defect Interactions in the Highly-Ordered Structural Transition Metal Dichalcogenide System 1T-TaS2
The 1T phase of tantalum disulfide (1T-TaS2) has a rich and complex charge density wave (CDW) phase character that has been broadly studied. CDWs are a highly correlated state between electron density and lattice distortion, originally predicted to only exist in one dimension. The discovery of CDWs …

Synthesis of 1T-Tantalum (IV) Sulfide and observation of charge density wave using scanning tunneling microscopy
… existence of a charge density wave (CDW) in 1T-Tantalum (IV) Sulfide (1T-TaS2). A member of the transition metal dichalcogenide (TMDC) family, 1T-TaS2 exhibit a periodic modulation of electronic charge density. Unlike bulk semiconductor or metals, lattice distortion in this low-dimensional …
