Spontaneous chiral ordering in titanium diselenide
… standard fabrication techniques. Four samples' photocurrent response to a 120 meV laser was subsequently measured as a function of temperature and laser power. The onset of the CPGE at approximately 174 K confirms the emergence of chiral order below the regular CDW transition at 197 K. …

Narrowband Photodetection in the Short-wavelength Infrared with a Plasmon-induced Hot Electron Device
… patterned on a silicon substrate, the absorption response can be combined with plasmon-induced hot electron photocurrent generation. This yields a photodetector with a strongly resonant, narrowband photocurrent response in the infrared, limited at low frequencies by the Schottky barrier, not the …

Investigations of the optoelectronic behaviour of novel phthalocyanine Langmuir-Blodgett films.
… with interdigitated electrodes. The spectral photocurrent, conductivity, and activation energy under illumination were investigated for both materials. The electrical response of the films to temperature, voltage and gaseous environment is presented with the time dependent photocurrent …

Optical spectroscopy of conjugated polymers.
… fluorescence, photo-induced absorption and photocurrent response of the treated films has been used to model the behaviour of the photogenerated exciton after excitation. At the same time, the . probing sheds light on the mechanisms at work in the deceleration of the implanted ions and the …

TOWARD ENHANCED BIMODAL SENSING: TIO₂-COATED METALLIC NANOSTRUCTURES FOR ELECTROCHEMICAL ANDPHOTOELECTROCHEMICAL DETECTION
… surface coverage, and a significantly increased photocurrent response. These results confirmed the importance of sol aging as a key parameter in modulating the properties of TiO2. To expand the system's functionality, the films were subsequently modified with gold nanoparticles (AuNPs) …

Immobilising and Interfacing Poly(Heptazine Imide) Ionic Carbon Nitride for Photo(electro)catalytic Fuel and Chemical Production
… its application is still hindered by low photocurrent response and poor long-term stability due to its notably high recombination rates, inefficient charge separation and transport, and consequent photo-degradation. Moreover, its compatibility with bio-based systems for green fuel and …

Carrier manipulation in graphene/ferroelectric hybrid structures
… with Raman spectroscopy and scanning photocurrent measurements, the creation of potential steps in graphene at domain walls of the underlying ferroelectric is demonstrated. Carrier density modulations of approximately 5x 10^12 cm^-2 now provide a platform that offers graphene devices …
