From Misconceptions to Evidence: What Science Teachers Make Visible When Co-Designing Agentic Learning Apps
Nizam Kadir, Wei Ting Liow, Sumbul Khan +1
Science educators increasingly encounter AI tools that generate content, yet disciplinary teaching depends on eliciting learners' models, diagnosing misconceptions, interpreting ev…
Co-Designing Interdisciplinary Design Projects with AI
Wei Ting Liow, Sumbul Khan, Lay Kee Ang
Creating interdisciplinary design projects is time-consuming and cognitively demanding for teachers, requiring curriculum alignment, cross-subject integration, and careful sequenci…
Human or AI? Comparing Design Thinking Assessments by Teaching Assistants and Bots
Sumbul Khan, Wei Ting Liow, Lay Kee Ang
As design thinking education grows in secondary and tertiary contexts, educators face the challenge of evaluating creative artefacts that combine visual and textual elements. Tradi…
Unconventional tunnel magnetoresistance scaling with altermagnets
Zongmeng Yang, Xingyue Yang, Jianhua Wang +7
In conventional magnetic tunnel junctions (MTJs), the tunnel magnetoresistance (TMR) typically increases with barrier thickness as electron transmission in the antiparallel configu…
Strongly correlated multi-electron bunches from interaction with quantum light
Suraj Kumar, Jeremy Lim, Nicholas Rivera +4
Strongly correlated electron systems are a cornerstone of modern physics, being responsible for groundbreaking phenomena from superconducting magnets to quantum computing. In most…
Electrical transport and persistent photoconductivity in monolayer MoS2 phototransistors
Antonio Di Bartolomeo, Luca Genovese, Tobias Foller +6
We study electrical transport properties in exfoliated molybdenum disulfide (MoS2) back-gated field effect transistors at low drain bias and under different illumination intensitie…
Relativistic space-charge-limited current for massive Dirac fermions
Y. S. Ang, M. Zubair, L. K. Ang
A theory of relativistic space-charge-limited current (SCLC) is formulated to determine the SCLC scaling, , for a finite bandgap Dirac material of length bias…
Current-temperature scaling for a Schottky interface with non-parabolic energy dispersion
Y. S. Ang, L. K. Ang
In this paper, we study the Schottky transport in narrow-gap semiconductor and few-layer graphene in which the energy dispersions are highly non-parabolic. We propose that the cont…
Electron Thermionic Emission from Graphene and a Thermionic Energy Converter
Shi-Jun Liang, L. K. Ang
In this paper, we propose a model to investigate the electron thermionic emission from a single-layer graphene (ignoring the effects of substrate) and to explore its application as…
Transition from ultrafast laser photo-electron emission to space charge limited current in a 1D gap
Yangjie Liu, L. K. Ang
A one-dimensional (1D) model has been constructed to study the transition of the time-dependent ultrafast laser photo-electron emission from a flat metallic surface to the space ch…
