Title: Flexible β‐Ga 2 O 3 Nanomembrane Schottky Barrier Diodes
Abstract

Here, high power flexible Schottky barrier diodes (SBDs) are demonstrated on a plastic substrate using single crystalline β‐Ga2O3nanomembranes (NMs). In order to realize flexible high power β‐Ga2O3SBDs, sub‐micron thick freestanding β‐Ga2O3NMs are created from a bulk β‐Ga2O3substrate and transfer‐printed onto the plastic substrate via a microtransfer printing method. It is revealed that the material property of β‐Ga2O3NMs such as crystal structure, electron affinity, and bandgap remains unchanged compared with its bulk properties. Flexible β‐Ga2O3SBDs exhibit the record high critical breakdown field strength (Ec) of 1.2 MV cm−1in the flat condition and 1.07 MV cm−1ofEcunder the bending condition. Overall, flexible β‐Ga2O3SBDs offer great promise for future flexible energy convergence systems and are expected to provide a much larger and more versatile platform to address a broader range of high‐performance flexible applications.

  2. Abstract

    Multidimensional power devices can achieve performance beyond conventional limits by deploying charge‐balanced p‐n junctions. A key obstacle to developing such devices in many wide‐bandgap (WBG) and ultra‐wide bandgap (UWBG) semiconductors is the difficulty of native p‐type doping. Here the WBG nickel oxide (NiO) as an alternative p‐type material is investigated. The acceptor concentration (NA) in NiO is modulated by oxygen partial pressure during magnetron sputtering and characterized using a p‐n+heterojunction diode fabricated on gallium oxide (Ga2O3) substrate. Capacitance and breakdown measurements reveal a tunableNAfrom < 1018 cm−3to 2×1018 cm−3with the practical breakdown field (EB) of 3.8 to 6.3 MV cm−1. ThisNArange allows for charge balance to n‐type region with reasonable process latitude, andEBis high enough to pair with many WBG and UWBG semiconductors. The extractedNAis then used to design a multidimensional Ga2O3diode with NiO field‐modulation structure. The diodes fabricated with two differentNAboth achieve 8000 V breakdown voltage and 4.7 MV cm−1average electric field. This field is over three times higher than the best report in prior multi‐kilovolt lateral devices. These results show the promise of p‐type NiO for pushing the performance limits of power devices.

  3. Abstract

    High quality dielectric‐semiconductor interfaces are critical for reliable high‐performance transistors. This paper reports the in situ metal–organic chemical vapor deposition of Al2O3on β‐Ga2O3as a potentially better alternative to the most commonly used atomic layer deposition (ALD). The growth of Al2O3is performed in the same reactor as Ga2O3using trimethylaluminum and O2as precursors without breaking the vacuum at a growth temperature of 600 °C. The fast and slow near interface traps at the Al2O3/β‐Ga2O3interface are identified and quantified using stressed capacitance–voltage (CV) measurements on metal oxide semiconductor capacitor (MOSCAP) structures. The density of shallow and deep level initially filled traps (Dit) are measured using ultraviolet‐assisted CV technique. The average Ditfor the MOSCAP is determined to be 6.4×1011cm−2eV−1. The conduction band offset of the Al2O3/ Ga2O3interface is also determined from CV measurements and found out to be 1.7 eV which is in close agreement with the existing literature reports of ALD Al2O3/Ga2O3interface. The current–voltage characteristics are also analyzed and the average breakdown field is extracted to be approximately 5.8 MV cm−1. This in situ Al2O3dielectric on β‐Ga2O3with improved dielectric properties can enable Ga2O3‐based high‐performance devices.

  4. Abstract

    The anisotropic dielectric functions (DF) of corundum structuredm-planeα-(AlxGa1−x)2O3thin films (up tox= 0.76) grown onm-plane sapphire substrate by metalorganic CVD have been investigated. IR and visible–UV spectroscopic ellipsometry yields the DFs, while X-ray diffraction revealed the lattice parameters (a,m,c), showing the samples are almost fully relaxed. Analysis of the IR DFs from 250 to 6000 cm−1by a complex Lorentz oscillator model yields the anisotropic IR active phononsEuandA2uand the shift towards higher wavenumbers with increasing Al content. Analyzing the UV DFs from 0.5 to 6.6 eV we find the change in the dielectric limitsεand the shift of the Γ-point transition energies with increasing Al content. This results in anisotropic bowing parameters forα-(AlxGa1−x)2O3ofb= 2.1 eV andb∣∣= 1.7 eV.

  5. Abstract

    In this work, we report a simplified method to measure thermal conductivity from the typical Raman thermometry method by employing a much simpler dispersion relationship equation and the Debye function, instead of solving the heat equation. Unlike the typical Raman thermometry method, our new method only requires monitoring of the temperature-dependent Raman mode shifting without considering laser power-dependent Raman mode shifting. Thus, this new calculation method offers a simpler way to calculate the thermal conductivity of materials with great precision. As a model system, theβ-Ga2O3nanomembrane (NM) on a diamond substrate was prepared to measure thermal conductivity ofβ-Ga2O3NMs at different thicknesses (100 nm, 1000 nm, and 4000 nm). Furthermore, the phonon penetration depth was investigated to understand how deep phonons can be dispersed in the sample so as to guide the dimensional design parameter of the device from the thermal management perspective.
