A Study on Word Sense Disambiguation Using Bidirectional Recurrent Neural Network for Korean Language

Jihong Min, Joon-Woo Jeon, Kwangho Song, Yoo Sung Kim

Word sense disambiguation(WSD) that determines the exact meaning of homonym which can be used in different meanings even in one form is very important to understand the semantical meaning of text document. Many recent researches on WSD have widely used NNLM(Neural Network …

Low resistance and thermally stable Ti/Al-based Ohmic contacts to N-face n-GaN for vertical light-emitting diodes by using Ti(Ga) solid solution and TiN layers

Joon-Woo Jeon, Woong-Sun Yum, Tae‐Yeon Seong, Sang Youl Lee et autres

The authors report on the formation of highly reliable Ti/Al-based ohmic contacts to N-face n-GaN for high-performance vertical light-emitting diodes by using Ti(Ga) solid solution and TiN layers. The Ti(Ga) solid solution layer is used to minimize the outdiffusion of Ga atoms …

Highly Reliable Ohmic Contacts to N-Polar n-Type GaN for High-Power Vertical Light-Emitting Diodes

Joon-Woo Jeon, Sang Youl Lee, June-O Song, Tae‐Yeon Seong

We report on the formation of highly reliable Ti/Al-based Ohmic contacts to N-polar n-GaN for vertical light-emitting diodes via laser-annealing. All as-deposited samples are Ohmic with specific contact resistances of 1.1 - 4.3 × 10-4Ω cm2. After annealing at 250°C, unlike the …
