Summary
This study explores near-field radiative heat transfer between Weyl semimetal/hBN structures. Enhanced heat transfer is achieved through coupled plasmonic and hyperbolic modes, offering tunable nanoscale thermal management solutions.
Area of Science:
- Condensed Matter Physics
- Nanoscale Heat Transfer
- Materials Science
Background:
- Weyl semimetals (WSMs) exhibit unique optical properties driving research.
- Near-field radiative heat transfer (NFRHT) is crucial for nanoscale thermal management.
- Hyperbolic materials (hBN) possess distinct electromagnetic characteristics.
Purpose of the Study:
- Investigate NFRHT between WSM/hBN multilayer structures.
- Analyze the coupling between WSM surface plasmons and hBN hyperbolic modes.
- Explore tunability of NFRHT via WSM properties and structural parameters.
Main Methods:
- Theoretical study of NFRHT using coupled surface plasmon polaritons (SPPs) and hyperbolic phonon polaritons (HSPPs).
- Modeling of WSM/hBN multilayer structures.
- Analysis of heat transfer coefficient (HTC) dependence on material properties and geometry.
Main Results:
- WSM/hBN structures exhibit enhanced NFRHT due to combined SPPs, epsilon-near-zero (ENZ) effects, and hyperbolic modes (HSPPs).
- A high total HTC of 1.80 × 104 W K-1 m-2 at 10 nm separation was achieved.
- NFRHT is highly tunable by adjusting the Fermi level and Weyl node count of WSMs.
Conclusions:
- WSM/hBN multilayer structures significantly enhance NFRHT compared to pure WSM or hBN.
- The findings provide a pathway for advanced thermal management in nanoscale WSM-based devices.
- Tunability offers design flexibility for optimizing heat transfer in nanophotonic systems.

Biasing metal-semiconductor junctions involves applying a voltage across the junction. Specifically, the metal is connected to a voltage source, while the semiconductor is grounded. This technique is essential for controlling the direction and magnitude of current flow in electronic devices, including diodes, transistors, and photovoltaic cells.
In Schottky junctions, where the semiconductor is n-type, applying a positive voltage to the metal relative to the semiconductor reduces its Fermi...

The contact of metal and semiconductor can lead to the formation of a junction with either Schottky or Ohmic behavior.
Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...

In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

Just as interesting as the effects of heat transfer on a system are the methods by which the heat transfer occur. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice box. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet, every heat transfer takes place by only three methods: conduction, convection, and radiation.
