Room-temperature optoelectronic devices that operate at short-wavelength and mid-wavelength infrared ranges (one to eight micrometres) can be used for numerous applications. To achieve the range of operating wavelengths needed for a given application, a combination of materials with different bandgaps (for example, superlattices or heterostructures) or variations in the composition of semiconductor alloys during growth are used. However, these materials are complex to fabricate, and the operating range is fixed after fabrication. Although wide-range, active and reversible tunability...

Javey Lab: Researchers Demonstrate New Semiconductor Device Possibilities using Black Phosphorus

August 11, 2021

Stress and strain, applied in just the right manner, can sometimes produce amazing results.

That is what researchers, led by a team at UC Berkeley’s Department of Electrical Engineering and Computer Sciences, discovered about an emerging semiconductor material — black phosphorus (BP) — used to make two types of optoelectronic devices: light emitting diodes (LEDs) and photodetectors.

Under mechanical strain, BP can be induced to emit or detect infrared (IR) light in a range of desirable wavelengths — 2.3 to 5.5 micrometers, which spans the short- to mid-wave IR — and to do so...

In recent years, there has been tremendous progress in large-scale mechanically flexible electronics, where electrical components are fabricated on non-crystalline substrates such as plastics and glass. These devices are currently serving as the basis for various applications such as flat-panel displays, smart cards, and wearable electronics.

In this thesis, a promising approach using chemically synthesized nanomaterials is explored to overcome various obstacles current technology faces in this field. Here, we use chemically synthesized semiconducting nanowires (...
