Absorption and desorption of deuterium on graphite at elevated temperatures

Deuterium thermal desorption from carbon based materials: A comparison of plasma exposure, ion implantation, gas loading, and C–D codeposition

“…Peaks at about the same temperatures and similar shift of TDS with increase of T abs were observed in [15]: there were only peaks with T m =550 K and 750 K at T abs =473 K, but peaks with T m =950 K and 1200 K appeared at T abs =650 K and 1100 K, respectively. Loading at higher temperatures of 1500 K [16] and 1170 K [17] led to release at even higher temperatures in the interval of 1000-1500 K and 1100-2100 K respectively.…”

“…An overview on hydrogen trapping and release is given in [1]. TDS after ion implantation [2][3][4][5][6][7][8][9][10], plasma irradiation [11][12][13][14], loading from gas [15][16][17], and co deposition of C-H films are often investigated. Experimental TDS sometimes seriously differ.…”

Dynamic Monte-Carlo modeling of hydrogen isotope reactive–diffusive transport in porous graphite

“…Many detailed macroscopic models have been proposed to study hydrogen isotope inventory and transport in porous graphite [1][2][3][4] and hydrocarbon formation and transport in graphite [8]. These models use rate constants for transport from experiments [9][10][11][12][13]7], some of which still need theoretical explanations. There exists many microscopic models [14][15][16][17] using MD with either empirical potentials or density functional theory and they give an insight into the microscopic mechanisms studied in graphite.…”
