Electromagnetic Interference (EMI): At the nanometer scale, even tiny electromagnetic fields can cause significant disruption to signal pathways. Crosstalk: This occurs when a signal transmitted on one nanowire induces an undesirable effect on another nearby nanowire. Signal Attenuation: Signals can lose strength over long distances or through various materials, becoming weaker and less reliable. Reflection and Refraction: Discontinuities in nanomaterials can cause signal reflections, leading to interference and data loss. Thermal Noise: Increased heat at the nanoscale can add noise to the signal, affecting its integrity.
