Synthesis, tribology, electro-tribology and mechanical performance of ti2alc and ti3alc2 max phases thin films
(Pontificia Universidad Católica del Perú, 2023-01-26)
This thesis investigates the synthesis, mechanical properties, tribological and electro-tribological
behavior of Ti2AlC and Ti3AlC2 MAX phases in the form of thin films. The thin films were obtained by
deposition of a ...
Contribution to the Tb-doped AlNxOy:H/c-Si(p) interface study using Surface Photovoltage (SPV) techniques for potential photovoltaic applications
(Pontificia Universidad Católica del Perú, 2023-07-10)
Hydrogenated Aluminum Oxynitride (AlNxOy:H) is a versatile material for the surface passivation of crystalline silicon (c-Si). The capability of having positive or negative fixed charges makes AlNxOy:H a suitable material ...
Riesgo radiológico debido a la radiactividad natural y exhalación de radón de suelos y materiales de construcción peruanos
(Pontificia Universidad Católica del Perú, 2023-07-06)
La exposición al Radón es una preocupación importante debido a su papel en el aumento del riesgo de cáncer de pulmón. Para evaluar el riesgo de exposición, es necesario realizar mediciones de Radón en el aire interior de ...
Testing pALPIDE sensors for particle detection and Characterization of a Laser beam using a webcam CMOS sensor
(Pontificia Universidad Católica del Perú, 2023-01-16)
The upgrade program of the Large Hadron Collider (LHC) was implemented during the second Long Shutdown program (2019/2020). For this program, the ALICE Collaboration (A Large Ion Collider Experiment) proposed, among others, ...
Preparación y optimización de películas delgadas de sistemas de carbono-sílice dopados con tierras raras para aplicaciones luminiscentes
(Pontificia Universidad Católica del Perú, 2022-02-01)
El uso de elementos de tierras raras (RE) en materiales de luminiscencia ha permitido
introducir mejoras en diversas aplicaciones. En iluminación, por ejemplo, los fósforos
amarillos YAG (Y3Al5O12:Ce3+) son ampliamente ...
Coherencia como recurso en los sistemas cuánticos abiertos
(Pontificia Universidad Católica del Perú, 2022-07-26)
In this thesis, we address open quantum systems subjected to Markovian and non-
Markovian evolutions. We diagnose these two regimes using the relative entropy of
coherence. We specially address the case of two qubits ...
From light neutrino decay phenomenology to muon neutrino cross-section measurement at MINERvA experiment
(Pontificia Universidad Católica del Perú, 2022-08-15)
This thesis tackles two essential topics of neutrino physics: neutrino decay and
neutrino cross-section measurement. First, the invisible and visible neutrino
decay is analyzed through a phenomenological approach, ...
Optical and luminiscent properties of terbium / ytterbium doped aluminum oxynitride and terbium doped aluminum nitride thin films
(Pontificia Universidad Católica del Perú, 2020-08-06)
In the present thesis the optical and light emission properties of two systems consisting of Tb3+ and Yb3+ doped amorphous AlOxNy thin films and Tb3+ doped polycrystalline AlN thin films were analyzed. In the two ions system, ...
A study on the response of the LR-115 detector exposed inside a diffusion chamber and in unconventional bare mode
(Pontificia Universidad Católica del Perú, 2021-12-17)
Several methodologies for radon concentration measurements have been used for monitoring
radon in homes and workplaces to minimize health hazards due to indoor radon
exposure. One of them is the Nuclear Track Methodology ...
