It is found that the temperature rise due to high current operation causes two effects: the current gain continuously declines after the base push-out is complete; and the negative differential resistance phenomenon occurs in the transistor current-voltage saturation region.
This behavior is indicative of transistor action in single molecules.
This technique enables us to investigate the role of defects in transistor performance.
These results also highlight the significant thermal gradients within the transistor.
Therefore, a transistor designed as partially depleted can behave as fully depleted.
The amorphous transistor materials can support such large strains because they lack a mechanism for dislocation motion.

What is the quantum confinement effect?
10 answers
The quantum confinement effect is a phenomenon observed in semiconductor materials, where the electronic and optical properties of the material are significantly altered due to the spatial confinement of charge carriers (electrons and holes) within dimensions that are comparable to the de Broglie wavelength of the carriers. This confinement leads to the discretization of energy levels, a departure from the continuous energy bands found in bulk materials. In practical terms, quantum confinement can manifest in various forms depending on the dimensionality of the confinement: in one dimension as quantum wells, in two dimensions as quantum wires, and in three dimensions as quantum dots (QDs). Each form of confinement restricts the motion of charge carriers in one or more dimensions, leading to distinct changes in the material's physical properties. For instance, quantum dots, which exhibit three-dimensional confinement, show size-dependent optical and electronic properties because the energy levels of the dots can be tuned by changing their size. This tunability is crucial for applications in near-field thermal radiation, light-emitting diodes (LEDs), and thin-film transistors. Quantum confinement effects are not only limited to altering electronic and optical properties but also influence the thermodynamic behavior of materials. For example, specific heat can exhibit unique features under spatial confinement, indicating phase transitions at certain temperatures. Moreover, the effect plays a significant role in enhancing the performance of semiconductors by tuning defect levels through strategies like hydrogen doping in nanostructures, thereby optimizing their electronic applications. Furthermore, quantum confinement can lead to the observation of quantum confinement effects in disordered materials, such as amorphous thin-film transistors, where it affects the field-effect mobility and device characteristics. It also impacts the linewidth broadening in metal halide perovskites, suggesting that quantum confinement is not a limiting factor in achieving ultrahigh color purity in next-generation LEDs. Additionally, the effect is evident in the blue shift of energy gaps in thin films, confirming its presence through spectroscopy experiments. In summary, the quantum confinement effect is a fundamental phenomenon that significantly influences the physical properties of nanostructured materials, with wide-ranging implications for electronic, optical, and thermodynamic applications.

What are good papers that explain the delta method of minimizing offset thermal EMFs?
5 answers
The delta method for minimizing offset thermal EMFs is well explained in the paper by Rodenbeck et al., where they introduce a technique called "delta modulation" (DM) to improve the sensitivity of RF subsamplers in radar and coherent receiver applications.
