Where Do Crystal Graph Networks Fail? A Space-Group-Resolved Error Analysis of Band Gap Prediction with a Simple Edge-Aware GNN: Crystal-X
Graph neural networks (GNNs) for crystal property prediction are typically evaluated by a single aggregate error, which can mask where, and for which classes of materials, these models fail. In this study, we present a space-group-, centering-type-, and band gap-resolved error analysis of GNN band…

Growth of highly conductive Al-rich AlGaN:Si with low group-III vacancy concentration
The impact of AlGaN growth conditions on AlGaN:Si resistivity and surface morphology has been investigated using metalorganic chemical vapor deposition. Growth parameters including growth temperature, growth rate, and trimethylindium (TMI) flow have been systematically studied to minimize the…
