TriGen: NPU Architecture for End-to-End Acceleration of Large Language Models based on SW-HW Co-Design
Jonghun Lee, Junghoon Lee, Hyeonjin Kim +5
Recent studies have extensively explored NPU architectures for accelerating AI inference in on-device environments, which are inherently resource-constrained. Meanwhile, transforme…
Probing Intrinsic Elastic Properties of Multilayer Graphene -- a New Mechanical Constant
Yun Hwangbo, Seong-jae Jeon, Young-Woo Son +1
We present measurements on in-plane Young's modulus and the Grüneisen parameter of multilayer graphene with varying number of layers, obtained through {\it in situ} bulge tests. A…
A van der Waals material exhibiting room temperature broken inversion symmetry with ferroelectricity
Fabia F. Athena, Cooper A. Voigt, Mengkun Tian +8
Since the initial synthesis of van der Waals two-dimensional indium selenide was first documented in 1957, five distinct polymorphs and their corresponding polytypes have been iden…
Natural Hyperbolicity of Hexagonal Boron Nitride in the Deep Ultraviolet
Bongjun Choi, Jason Lynch, Wangleong Chen +6
Hyperbolic media enable unique optical phenomena including hyperlensing, negative refraction, enhanced photonic density of states (PDOS), and highly confined polaritons. While most…
