Characteristics of CVD grown 2H (semiconducting phase) MoTe₂ sheets         

Product Description

2H semiconducting phase few-layer MoTe₂ (3-6 layers) has been grown on 1cm² size c-cut sapphire substrates using low-pressure chemical vapor deposition technique (LPCVD). Grown sheets can also be transferred onto other substrates such as quartz, SiO₂/Si, PET, metals, and others on request. Few-layer MoTe₂ reach full area coverage on sapphire, exhibit outstanding environmental stability, surface smoothness, and uniformity. Grown sheets are environmentally stable and exhibit band gap between bulk (0.6 eV) and monolayer (1.1 eV). 

Special note: Despite extensive R&D efforts, CVD grown monolayer MoTe₂ are environmentally rather unstable due to uncontrollable defect characteristics. We are unable to provide monolayer thick MoTe₂ at this time.
