Description
Monolayer 2H-MoTe₂ FET Device
Device Structure:
Conductive Si Substrate / 300 nm SiO₂ Layer / 5 µm Gold Electrode Array / Monolayer 2H-MoTe₂
Device Description & Features:
High-Performance 2D Semiconductor: Molybdenum ditelluride (MoTe₂) in its 2H phase is a layered transition metal dichalcogenide (TMD) with a direct bandgap (~1.1 eV in monolayer form), making it suitable for high-performance electronic and optoelectronic applications.
Back-Gated FET Configuration: The SiO₂/Si back-gate structure provides efficient electrostatic control, enabling low-power operation, high field-effect mobility, and a high on/off current ratio.
Gold Electrode Array (5 µm Spacing): Facilitates uniform carrier injection while preserving the intrinsic transport properties of MoTe₂.
Monolayer Structure: Ensures strong light-matter interactions, leading to enhanced optoelectronic responses compared to bulk counterparts.
Semiconducting 2H Phase: The thermodynamically stable semiconducting phase of MoTe₂ offers excellent electrical performance with tunable electronic properties.
Applications:
High-Performance Field-Effect Transistors (FETs):
Monolayer MoTe₂ FETs exhibit high mobility and strong gate tunability, making them promising candidates for ultrathin and low-power nanoelectronics.
Flexible & Transparent Electronics:
The ultrathin nature of MoTe₂ makes it suitable for flexible transistors and transparent electronic devices.
Optoelectronic & Infrared Photodetector Applications:
The narrow bandgap (~1.1 eV) enables MoTe₂ to function as an infrared-sensitive material, ideal for photodetectors and near-infrared optoelectronics.
Quantum Transport & Spintronics:
MoTe₂’s layered structure and strong spin-orbit coupling allow potential applications in quantum electronics and spintronic devices.
