Observation of point defect and carrier lifetime distributions in hydrogen or helium ion implanted SiC PiN diodes for suppression of bipolar degradation
Authors: Kato Masashi , Li Tong , Sakane Hitoshi , Harada Shunta
Published: January 2025

We have reported that hydrogen or helium ion implantation can suppress the expansion of stacking faults in SiC devices. These results suggest that point defects caused by ion implantation are an important factor in suppressing the expansion. On the other hand, the depth distribution of point defects introduced by implantation of these ions has not been fully elucidated. In this study, we evaluated the point defect and carrier lifetime distributions inside SiC diodes implanted with hydrogen or helium ions by cathodoluminescence and microscopic free carrier absorption methods.

Published: January 2025

This research explores the feasibility of employing thin AlGaN barriers as a substitute for the conventional gate recess process in GaN MIS-HEMTs. By systematically varying the AlGaN aluminum concentrations, we successfully fabricated devices exhibiting enhancement-mode (E-mode) operation. A ferroelectric charge trap gate stack (FEG gate stack) was integrated to elevate the threshold voltage (V
th) and enhance device performance. Experimental characterization reveals the effectiveness of this approach in simplifying the fabrication process while maintaining desirable device characteristics. The influence of AlGaN barrier composition on threshold voltage, output current, breakdown voltage, double sweep test, and dynamic on-resistance is comprehensively analyzed.

The interface between the electron transport layer (ETL) and the perovskite layer is essential for fabricating efficient and stable perovskite solar cells (PSCs). In this study, we introduced a bilayer ETL of W-doped ZnO and single crystalline anatase TiO2 nanoparticles (average diameter = 6–10 nm) to mitigate the degradation between W-doped ZnO ETL and MA-containing perovskite layer. After 12 h of annealing at 85 °C, the perovskite grown on the bilayer exhibited strong perovskite peaks, indicating a significant slowdown in decomposition. Moreover, the bilayer device demonstrated superior thermal stability, retaining over 60% of their initial power conversion efficiency (PCE) after 24 h of annealing, while the W-doped ZnO single-layer device lost all efficiency. PSCs with the W-doped ZnO/Anatase TiO2 bilayer achieved PCE of 16.63%, compared to 11.88% for the W-doped ZnO single layer. This bilayer application offers a promising pathway for improving both the efficiency and stability for perovskite-based optoelectronic devices.

Published: January 2025

This paper presents a hardware inference accelerator architecture of quantized deep neural networks (DNN). The proposed accelerator implements all computation in a quantize version of DNN including linear transformations like matrix multiplications, nonlinear activation functions such as ReLU, quantization and dequantization operation. The hardware accelerator of quantized DNN consists of matrix multiplication core which is implemented in systolic array architecture, and the QDR core for computing the operation of quantization, dequantization, and ReLU. This proposed hardware architecture is implemented in Verilog Hardware Description Language (HDL) code using modelsim. To validate, we simulated the quantized DNN using Python programming language and compared the results with our proposed hardware accelerator. The result of this comparison shows a very slight difference, confirming the validity of our quantized DNN hardware accelerator.

This research discusses the design and evaluation of a user interface (UI) prototype for the livestock management application of PT XYZ. Information systems have become key to effectiveness and efficiency in various industries. However, often the design of information systems is isolated and lacks consideration for user experience (UX). PT XYZ faces challenges in manually managing livestock and aims to develop an effective system. This study uses prototype design methods and heuristic evaluation to create a UI/UX that meets business needs, is easy to use, and enjoyable. The evaluation results show that this design solution aligns with PT XYZ's business processes and is preferred by users. This indicates that designing using prototype methods and heuristic evaluation can help develop applications that are tailored to needs, effective, efficient, and liked by users.

Perancangan Arsitektur Sistem Informasi Menggunakan Framework TOGAF (Studi Kasus pada GITJ Margorejo Pati)
Authors: Fransiskus Ariel Ade , Tanaamah Andeka Rocky
Published: January 2025

Currently, the Evangelical Church in Java (GITJ Margorejo Pati) has not implemented an information system in carrying out congregation data collection activities, budgets, budget plans, activity plans and so on. The activities carried out in each field are assisted by computers and there is no integrated information system between one field and another. So accessing data simultaneously in each field cannot yet be done, apart from that, the data processing system currently used causes the required data and information to not be timely due to the difficulty of accessing data and information. For this reason, it is necessary to design an enterprise architecture using TOGAF ADM. TOGAF ADM is a method that can be used to design enterprise architecture. Each stage in TOGAF ADM can be carried out correctly if the business processes within the organization are truly understood and able to be identified completely and correctly. This enterprise architecture modeling provides guidance in creating a blueprint for developing information systems for data, applications, business and technology.

Saat ini pada Gereja Injili di Tanah Jawa (GITJ Margorejo Pati) belum menerapkan sistem informasi dalam melakukan kegiatan pendataan jemaat, anggaran, rencana anggaran, rencana kegiatan dan sebagainya. Aktivitas-aktivitas yang dilakukan pada setiap bidang tersebut dibantu dengan komputer dan belum adanya sistem informasi yang terintegrasi antara satu bidang dengan bidang lainnya. Sehingga dalam pengaksesan data secara bersama-sama dalam setiap bidang belum bisa dilakukan, selain itu dengan sistem pengolahan data yang digunakan saat ini menyebabkan data dan informasi yang dibutuhkan tidak tepat pada waktunya karena sulitnya pegaksesan data dan informasi. Untuk itu perlu dibuat perancangan arsitektur enterpise menggunakan TOGAF ADM. TOGAF ADM merupakan salah satu metode yang bisa digunakan untuk melakukan perancangan arsitektur enterprise. Setiap tahapan pada TOGAF ADM dapat dilakukan secara benar apabila proses bisnis yang ada di dalam organisasi benar-benar harus dipahami dan mampu di identifikasi secara lengkap dan benar. Pemodelan arsitektur enterprise ini, memberikan panduan dalam membuat cetak biru untuk pengembangan sistem informasi untuk data, aplikasi, bisnis, dan teknologi.

Published: January 2025

Garbage refers to items no longer used and results from everyday human activities. Waste is divided into two types: organic and inorganic. However, many children cannot sort these types of waste and do not understand the benefits. To address this issue, a 3D animation video was created using the Learning Before Play After (LBPA) method, which emphasizes learning before playing. The LBPA method helps children focus and engage in learning about waste sorting. This study aims to improve children's understanding of waste sorting. Testing results show a significant increase in understanding, with 88% of 100 children successfully grasping the concept of sorting organic and inorganic waste. This system has proven effective and positively impacts children, helping them sort and dispose of waste correctly.
