Este artículo pretende ser complemento y continuación de mis anteriores trabajos sobre la figura de Petrus Hispanus O. P., Auctor Summularum. Comienzo presentando algunos nuevos documentos relacionados con las cuestiones ya examinadas en mis artículos de 1997 y 2001. A continuación, me ocupo de las cuestiones aplazadas en el artículo de 2001: los problemas relativos a la figura de “Petrus Ferrandi” y su posible relación con el “auctor Summularum”, así como los argumentos de Tugwell contra la hiptesis de la posible identidad de estas dos figuras, examinados ahora desde la perspectiva del autor de la Legenda prima. Tras analizar testimonios procedentes de muy diversos ámbitos, afirmo, por una parte, que la hiptesis de la identidad entre “Petrus Ferrandi” y “Petrus Hispanus” podría ser correcta y, por otra parte, que no hay argumentos concluyentes que obliguen a afirmar con seguridad que el autor de la Legenda prima es Pedro Ferrando. Aunque los análisis no permiten por el momento determinar si es “Petrus Alfonsi” o “Petrus Ferrandi” el “auctor Summularum”, los testimonios recogidos y las conexiones establecidas contribuirán, sin duda, a orientar futuras investigaciones en torno a la figura de “Petrus Hispanus”.

Conventional Si complementary-metal-oxide-semiconductor (CMOS) scaling is fast approaching its limits. The extension of the logic device roadmap for future enhancements in transistor performance requires non-Si materials and new device architectures. III-V materials, due to their superior electron transport properties, are well poised to replace Si as the channel material beyond the 10nm technology node to mitigate the performance loss of Si transistors from further reductions in supply voltage to minimise power dissipation in logic circuits. However several key challenges, including a high quality dielectric/III-V gate stack, a low-resistance source/drain (S/D) technology, heterointegration onto a Si platform and a viable III-V p-metal-oxide-semiconductor field-effect-transistor (MOSFET), need to be addressed before III-Vs can be employed in CMOS.
This Thesis specifically addressed the development and demonstration of planar III-V p-MOSFETs, to complement the n-MOSFET, thereby enabling an all III-V CMOS technology to be realised. This work explored the application of InGaAs and InGaSb material systems as the channel, in conjunction with Al2O3/metal gate stacks, for p-MOSFET development based on the buried-channel flatband device architecture. The body of work undertaken comprised material development, process module development and integration into a robust fabrication flow for the demonstration of p-channel devices.
The parameter space in the design of the device layer structure, based around
the III-V channel/barrier material options of Inx≥0.53Ga1-xAs/In0.52Al0.48As and Inx≥0.1Ga1-xSb/AlSb, was systematically examined to improve hole channel transport. A mobility of 433 cm

Films of piezoelectric PVDF and P(VDF-TrFE) were exposed to vacuum UV (115-300 nm VUV) and -radiation to investigate how these two forms of radiation affect the chemical, morphological, and piezoelectric properties of the polymers. The extent of crosslinking was almost identical in both polymers after -irradiation, but surprisingly, was significantly higher for the TrFE copolymer after VUV-irradiation. Changes in the melting behavior were also more significant in the TrFE copolymer after VUV-irradiation due to both surface and bulk crosslinking, compared with only surface crosslinking for the PVDF films. The piezoelectric properties (measured using d33 piezoelectric coefficients and D-E hysteresis loops) were unchanged in the PVDF homopolymer, while the TrFE copolymer exhibited more narrow D-E loops after exposure to either - or VUV-radiation. The more severe damage to the TrFE copolymer in comparison with the PVDF homopolymer after VUV-irradiation is explained by different energy deposition characteristics. The short wavelength, highly energetic photons are undoubtedly absorbed in the surface layers of both polymers, and we propose that while the longer wavelength components of the VUV-radiation are absorbed by the bulk of the TrFE copolymer causing crosslinking, they are transmitted harmlessly in the PVDF homopolymer.
