Following the success of Moore's predictions, we are approaching a limit in the miniaturization of semiconductors for computing materials. This has led to the exploration of various research paths in search of alternative computing paradigms, such as quantum computing, 3D transistors, molecular logic, and continuous logic. In this context, we propose a novel approach in which the dynamics of a...
Semiconductors exhibit distinctive electronic behavior governed by transitions across narrow bandgaps, typically 0 to a few electron volts. Upon optical or electrical excitation, electrons are promoted to the conduction band, leaving holes in the valence band. Luminescence is produced when these electron–hole pairs recombine radiatively, emitting photons. Because emission efficiency depends...
Solid-state lithium-ion batteries are recognized as the emerging battery technology of choice for electronics that store electrical energy, providing greater safety and compactness compared to standard lithium-ion batteries. The latter contains a liquid electrolyte, which leads to more leakages and other dangers. The advantages provide benefits to the emerging battery technology. The chances...
Narrow-bandgap two-dimensional (2D) semiconductors are promising for near- and far-infrared photodetection, particularly at telecommunication wavelengths, but their performance is often limited by high dark current, carrier recombination, and thermal noise. Here, we report a hybrid van der Waals phototransistor that overcomes these challenges by integrating contact-free palladium diselenide...
The scalability of superconducting quantum computers remains fundamentally constrained by decoherence mechanisms in Josephson junction-based qubits, with two-level system (TLS) defects at material interfaces representing a primary source of energy dissipation. While aluminum has served as the conventional electrode material for superconducting qubits, its limitations in coherence times and...
Nuclear batteries find applications in medical implants, sensor nodes, and are suited to deployment in extreme environments. Nuclear batteries made from alpha radiation sources offer the potential of higher energy density compared to beta-voltaic batteries. The mitigation of alpha particle damage to semiconductor charge collection structures remains a challenge, to extend the very short...
