“…The fundamental advantage of the SL thin‐film structures when fabricated using state‐of‐the‐art thin‐film techniques is that the individual layer thicknesses can be precisely tailored to a constant value; this is not necessarily possible for other nanostructured materials (e.g., nanoparticles) for which considerably wider dimension variations are typically seen. Indeed, exciting/enhanced material properties and abrupt changes in material characteristics have been reported for various thin‐film SL materials owing to interface effects and quantum confinement phenomena …”

Combined atomic/molecular layer deposition (ALD/MLD) technique enables the engineering of inorganic-organic superlattices with atomic/molecular layer accuracy for the individual layer thicknesses. Here we demonstrate how the optical and electronic properties of e-Fe 2 O 3 thin films can be gradually tuned with an insertion of monomolecular organic layers. In our e-Fe 2 O 3 : benzene superlattice (SL) structures the thickness of individual iron oxide layers varies in the range of 1-17 nm. With decreasing e-Fe 2 O 3 layer thickness, that is, SL period, the films become more transparent. Moreover revealed from the UV-vis spectra is that the indirect optical bandgap increases from %2.0 eV for e-Fe 2 O 3 up to %2.3 eV for the SL films with the shortest SL period. We foresee that the ALD/MLD approach presented here for the e-Fe 2 O 3 -benzene thin films can be exploited in fabricating many other interesting hybrid material systems with controlled optoelectronic properties.

“…To address this challenge in this work a miniaturized differential photoacoustic module (PAM) with two identical cylindrical resonators was designed to detect trace amounts of methane (CH 4 ). The PAM employed a novel, custom made ICLED with a 22-stage interband cascade active core, which emitted up to 2.8 mW of cw optical radiation at ~3.2 μm in a Lambertian profile at T = 25 °C and I = 600 mA [40]. An Al-coated concave reflector was positioned adjacent to a cylindrical resonator to enhance the effective absorption length.…”

“…The maximum output power shown in the figure is limited by the compliance voltage of the current driver. Based on NRL's characterization of the total power emitted by the device in a Lambertian profile (up to 2.8 mW at I = 600 mA, which was obtained by dividing the collimated power by the collection efficiency) [40], at least 30% more collimated power would be produced using a different higher driver compliance voltage.…”

Compact photoacoustic module for methane detection incorporating interband cascade light emitting device

et al. 2017

A photoacoustic module (PAM) for methane detection was developed by combining a novel 3.2 μm interband cascade light emitting device (ICLED) with a compact differential photoacoustic cell. The ICLED with a 22-stage interband cascade active core emitted a collimated power of ~700 μW. A concave Al-coat reflector was positioned adjacent to the photoacoustic cell to enhance the gas absorption length. Assembly of the ICLED and reflector with the photoacoustic cell resulted in a robust and portable PAM without any moving parts. The PAM performance was evaluated in terms of operating pressure, sensitivity and linearity. A 1σ detection limit of 3.6 ppmv was achieved with a 1-s integration time.
