Graphene Defect & Quantum Transport Simulator

TOOL:
Gesture Action: Click any carbon bond to rotate it 90° (Stone-Wales defect) or click atoms to knock them out. Watch the violet quantum wavepacket scatter and localized mid-gap states concentrate charge.

Defects create localized π-electron accumulation, boosting target gas binding affinity by >400% compared to pristine graphene.

Sensory Signal Ratio: 4.85x Pristine
Local Density of States (LDOS) Spectrum E_Fermi @ 0.00 eV
Simulation Tuning Parameters
Applied Source-Drain Bias: 45 mV
Back-Gate Voltage (V_g): 0.80 V
Tight-Binding Hopping (t₀): 2.70 eV
The Defect Breakthrough: In pristine graphene, zero-gap Dirac cones mean low on/off ratios and inert chemical binding. When a Stone-Wales 5-7 ring defect forms, the local lattice strain breaks sublattice symmetry, creating mid-gap electronic states that trap molecules and elevate sensor sensitivity.
