"maintaining small, controlled barrier at metal/ semiconductor interface allows operation in contact-controlled mode, significantly improving long-term consistency... shifting current flow control from semiconductor channel to contact interface enables aging effect/ voltage shift resistance caused by trapped charges... stays stable even at ≤-4 V... silver contacts, multimodal transistor designs allow for more uniform current between devices/ simpler circuit architectures... OLED/ microLED displays, wearable sensors"
