PdTe2（PALLADIUM TELLURIDE）

PdTe₂ (Palladium Telluride) is an inorganic compound composed of palladium (Pd) and tellurium (Te). It belongs to the class of transition metal dichalcogenides (TMDs), a family of materials known for their unique electronic, optical, and thermal properties. PdTe₂ has a layered structure, which enables its exfoliation into thin films, making it a promising candidate for use in two-dimensional (2D) material applications.

Physical Properties

• Appearance: PdTe₂ typically appears as a metallic material with a dark metallic luster.
• Crystal Structure: PdTe₂ adopts a layered hexagonal crystal structure, similar to other TMDs. This allows for the exfoliation of the material into monolayers or few-layer forms, which is important for 2D material-based applications.
• Electrical Properties: PdTe₂ is a semimetal, exhibiting metallic conductivity. It has a high carrier mobility, making it suitable for use in high-speed electronic devices. Its semimetallic nature also makes it an attractive material for optoelectronics.
• Thermoelectric Properties: PdTe₂ is an efficient thermoelectric material, meaning it can convert heat into electricity. It is being studied for its potential in energy harvesting applications, such as waste heat recovery.
