Harnessing quantum asymmetry to regulate unidirectional heat flow. The quantum thermal diode, based on the interaction between a qutrit (a quantum system with three stable energy levels) and a ...

2. Experimental setup of the bridging-droplet thermal diode. (a) Photograph of the wicked copper plate possessing an array of wetted micropillars of dimensions 100 × 100 × 600 μm.

Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team ...

Figure 1 Ideal diode half wave rectification . So far, so good, but look at what can happen when there is storage charge in the diode:. Figure 2 Slow recovery diode half wave rectification . In this ...

However, making single-molecule diodes – the most basic of all electronic elements – has proved to be a difficult task. A single-molecule diode is a two-terminal electronic component that allows ...

Figure 3 Two LED drivers operating in series or parallel let you boost zener voltage or current. Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On ...

I n an idealized diode, no reverse current flows from cathode to anode when the device is reverse-biased. However, with real-world diodes, large amounts of stored charge can flow ...

These single-stage instrumentation amplifiers accurately measure very small sense voltages across a wide range of common-mode voltages up to 26V while operating from a 2.7V to 5.5V supply. Automotive ...

A model of a quantum thermal diode based on a qubit and qutrit. The asymmetric design allows this system to behave as a thermal diode when connected between two thermal baths. Credit: APL Quantum ...
