The electric field dependence of emission rate the deep traps with level near Ec−0.6 eV, so-called E1 traps, was studied by means transient spectroscopy measurements over a wide range applied voltages. were initially introduced 900 °C ampoule annealing in molecular hydrogen. results indicate activation energy centers and ratio high-field to low-field electron rates at fixed temperature scale as square root field, suggesting that behave donors. possible microscopic nature view recent...
Ion beam fabrication of metastable polymorphs Ga2O3, assisted by the controllable accumulation disorder in lattice, is an interesting alternative to conventional deposition techniques. However, adjustability electrical properties such films unexplored. In this work, we investigated two strategies for tuning electron concentration ion created κ-polymorph: adding silicon donors implantation and hydrogen via plasma treatments. Importantly, all heat treatments were limited ≤600 °C, set thermal...

The electrical properties and deep trap spectra of semi-insulating Ga2O3(Fe) implanted with Si ions subsequently annealed at 1000 °C were investigated. A significant discrepancy was observed between the measured shallow donor concentration profile predicted by Stopping Power Range Ions in Matter simulations, indicating substantial compensation. Deep level transient spectroscopy revealed presence acceptors Ec −0.5 eV a ∼10¹⁷ cm−³, insufficient to fully account for Photocapacitance identified...
The stable beta polymorph Ga 2 O 3 was converted to gamma by ion irradiation. current–voltage characteristics show the is much more rad-hard.
Direct observation of capture cross-section is challenging due to the need extremely short filling pulses in two-gate Deep-Level Transient Spectroscopy (DLTS). Simple estimation can be done from DLTS and Admittance (AS) data, but it not feasible distinguish temperature dependence pre-exponential exponential parts emission rate equation with sufficient precision conducting a single experiment. This paper presents experimental data deep-levels $\beta$-Ga2O3 that has been gathered by our group...
Heterojunctions (HJs) of p-NiO/n-Ga 2 O 3 were prepared by deposition thin films p-NiO ion beam sputtering on bulk nominally undoped (100) oriented n-Ga samples cleaved from Czochralski-grown (010) crystal. Electrical properties and deep traps spectra studied compared with those obtained for similar Ni Schottky diodes. Characteristic features the NiO/Ga HJs are built-in voltage over V to 1 in diodes, a strong frequency dispersion capacitance due presence high density 10 18 cm −3 E c -0.16 eV...
Abstract. We present a summary on the current status of two inversion algorithms that are used in EARLINET for data collected with multiwavelength Raman lidars. These instruments measure backscatter coefficients at 355, 532, and 1064 nm, extinction 355 532 nm. Development these started 2000 when was founded. The based manually controlled optical which allows detailed sensitivity studies thus provides us comparably high quality derived products. allow to derive particle effective radius,...
