Aging and Electrical Stability of DNTT Honey‐Gated OFETs
Advanced Electronic Materials, EarlyView.DNTT honey‐gated organic transistors were fabricated and evaluated to assess short‐ and long‐term stability under electrical stress and aging. Short‐term transfer measurements (five days, 40 sweeps/day) showed minimal parameter shift, while extended measurements revealed gradual degradation over weeks.
