A new method for assessing the utility of powder bed fusion (PBF) feedstock
Mani Gonzalez, Pierre Giovanni; E. Gorji, Nima; Saxena, Prateek; Corfield, Martin; Clare, Adam; Rueff, Jean-Pascal; Bogan, Justin; Snelgrove, Matthew; Hughes, Greg; O'Connor, Robert; Raghavendra, Ramesh; Brabazon, Dermot (2020-01-29)Recycling metallic powders used in the additive manufacturing (AM) process is essential for reducing the process cost, manufacturing time, energy consumption, and metallic waste. In this paper, the focus is on pore formation ... -
Aluminium oxide formation via atomic layer deposition using a polymer brush mediated selective infiltration approach
Mani Gonzalez, Pierre Giovanni; Snelgrove, Matthew; McFeely, Caitlin; Lahtonen, K; Lundy, Ross; Hughes, Greg; Valden, M; McGlynn, Enda; Yadav, Pravind; Saari, J; Morris, Mike A; O Connor, Robert (2020-03-06)Area selective deposition (ASD) is an emerging method for the patterning of electronic devices as it can significantly reduce processing steps in the industry. A potential ASD methodology uses infiltration of metal precursors ... -
Analysis of Al and Cu salt infiltration into a poly 2-vinylpyridine (P2vP) polymer layer for area selective deposition applications
Mani Gonzalez, Pierre Giovanni (2020-01)This work is motivated by the desire to develop a semiconductor device patterning technology based on precursor infiltration into block copolymer materials. Developing an understanding of the preferential infiltration of ... -
Growth chemistry and electrical performance of ultrathin alumina formed by area selective vapor phase infiltration
Mani Gonzalez, Pierre Giovanni; Snelgrove, Matthew; McFeely, Caitlin; Hughes, Gregory; Weiland, C; Woicik, Joshep; Shiel, Kyle; Ornelas, Carlos; Solis-Canto, Óscar; Cherkaoui, K; Hurley, P; Yadav, Pravind; Morris, Michael; McGlynn, Enda; O'Connor, Rob (2022-09-28)The growth chemistry and electrical performance of 5 nm alumina films, fabricated via the area-selective vapor phase infiltration (VPI) of trimethylaluminum into poly(2-vinylpyridine), are compared to a conventional plasma ... -
Hard x-ray photoelectron spectroscopy study of copper formation by metal salt inclusion in a polymer film
Snelgrove, Matthew (2019-08-08)In this work we present the results of a hard x-ray photoelectron spectroscopy (HAXPES) study on the creation of metallic copper layers via metal-salt infiltration into a poly-2-vinylpyridine (P2VP) film. Metal salt inclusion ... -
Precise Definition of a “Monolayer Point” in Polymer Brush Films for Fabricating Highly Coherent TiO2 Thin Films by Vapor-Phase Infiltration
Mani Gonzalez, Pierre Giovanni; Lundy, Ross; Yadav, Pravind; Prochukhan, Nadezda; C Giraud, Elsa; F O’Mahony, Tom; Selkirk, Andrew; Mullen, Eleanor; Conway, Jim; Turner, Miles; Daniels, Stephen; Snelgrove, Matthew; Bogan, Justin; McFeely, Caitlin; O’Connor, Robert; McGlynn, Enda; Hughes, Greg; Cummins, Cian; A Morris, Michael (2020-10-06)In this work, we show that in order to fabricate coherent titania (TiO2) films with precise thickness control, it is critical to generate a complete polymer brush monolayer. To date, demonstrations of such dense polymer ... -
Recyclability of stainless steel (316 L) powder within the additive manufacturing process
E Gorji, Nima (2019-12-12)Using recycled powder during the additive manufacturing processes has been a matter of debate by several research groups and industry worldwide. If not significantly different from the feedstock, the recycled powder can ... -
Surface characterization of poly-2-vinylpyridine—A polymer for area selective deposition techniques
Snelgrove, Matthew (2019-09-02)Thin films of OH terminated poly-2-vinylpyridine (P2VP), a polymer with potential for infiltration mediated thin film deposition, area selective deposition (ASD), and small feature size development via block copolymer (BCP) ... -
Titanium infiltration into ultrathin PMMA brushes
Mani Gonzalez, Pierre Giovanni (2021-07-21)Vapor phase infiltration (VPI) is a bottom-up process that involves the infiltration of polymers, often using atomic layer deposition compatible precursors. By exposing a polymer to an organo-metallic precursor, area ...
